Situated just two miles from downtown Seattle, South Lake Union offers beautiful bayside and lakeside views, a scenic cityscape, and access to everything Seattle has to offer.
Nestled directly east of the Space Needle, Seattle Children’s Museum, Museum of Pop Culture, Memorial Stadium and more, this neighborhood is bikeable and walkable to some of Seattle’s greatest attractions. Aside from its location, South Lake Union offers immense perks. Just take a trip to Lake Union Park for access to 12 acres of lakefront property with a boat launch, beautiful walkways, and the Museum of History & Industry, or experience of one its incredible local restaurants.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

Property Ratings at Onni South Lake Union
Warning: STAY AWAY Warning: Avoid Onni South Lake Union Apartments If you're considering living at Onni South Lake Union, I strongly advise you to think twice. My experience with this building was nothing short of a nightmare, and it cost me nearly $15,000 to break the lease after signing what seemed like a promising agreement. Here’s why: False Promises, Rudeness, and Unprofessional Behavior When we first toured the property, the staff and leasing team were friendly and professional, eager to help us with anything we needed. However, after our first complaint about the conditions and our request to break the lease, their attitude changed drastically. They became rude, dismissive, and careless. What started as a seemingly professional relationship turned into complete disregard for our concerns. The moment we expressed dissatisfaction, the kindness vanished. They showed no empathy and refused to help, making the process of breaking the lease even more difficult. Health Issues and Abandonment Unfortunately, after breaking the lease, we had to leave Seattle for health reasons and never spent a single night in the apartment. We asked Onni to hold on to a couple of our furniture items while we sorted things out, but they discarded them without warning, claiming they only held onto them for 30 days. No one reached out to inform us about this policy. It felt like they wanted to make things as difficult as possible for us. Unsafe and Disturbing Environment What they don't tell you is that Onni South Lake Union isn't just a residential complex—it doubles as a hotel. This brings in a constant flow of transient guests who are not invested in the community, and it drastically changes the building’s atmosphere. The lobby and common areas are often crowded with groups of people who do not live there, which includes young women who appear to be using the space for gatherings that made us feel unsafe and uncomfortable. It felt more like a party venue than a place to call home. The combination of the hotel and constant strangers made the building feel less secure and far from the peaceful, upscale environment we expected. Facilities and Maintenance Neglect On top of that, the building’s facilities were a disaster. From the broken sauna to filthy pool areas and drainage problems, nothing was properly maintained. The building was not up to the standards that we were promised. The common areas reeked of marijuana, and there were safety hazards everywhere.

Hello there, We’re very sorry to hear about your experience and appreciate your feedback. We’re happy to review any discrepancies with you directly. If you have any further questions or would like to discuss this, feel free to reach out to us at OSLUresidentservices@onni.com or call us at (206) 428-3988. Thank you again for your feedback, and we’re committed to improving our service.
I have been a resident at Onni for over a year now, and have loved my time here so much! I am moving into a new unit in the building and appreciated the streamlined abilities of the staff, especially Sarah Ahn, in advocating to have the perfect apartment unit held for my partner and I until we could move in. Sarah has been there to support us, offer resources, and answer questions along the way. I highly recommend Onni not only for the amazing resident services team, but also for the incredible amenities and overall experience Onni provides while living in SLU!
Property Manager at Onni South Lake Union, Responded To This Review
Hi there! Thank you so much for this amazing review! We truly appreciate the time you've taken to highlight features of our community, building, and team here at OSLU. We want to continue providing you with an exceptional experience, so please do not hesitate to reach out should you ever have any questions or concerns. Thanks again for your recommendation and have a great day!
Onni is a great new building, but what makes it truly special is its guest services. Khadra, T, and Marlee make Onni a wonderful home to live in. Their kindness, reliability, and care elevate the experience in the building and bring joy to residents. This team makes all the difference in our experience! Whenever any issues or concerns come up, I can always count on them to understand and help. For example, Khadra was working on the night that we encountered a minor flood in our apartment, and she managed to get us help repairing it even though it was late and we’d arrived home in the middle of the night. Her help fixing this allowed us to prevent further damage and more serious problems, and allowed us to get a good night’s sleep knowing this was resolved by someone who genuinely demonstrated care and concern. It brings us so much peace of mind knowing that we have this level of support!

We want to continue providing you with an exceptional living experience, so please do not hesitate to contact us here at the office should you ever have any questions or concerns.
As a resident, I am extremely disappointed with the current state of the hallway in our building. The overwhelming smell of garbage is making it difficult to even walk through the hallway without feeling nauseous. It is disappointing to see such a lack of concern for the basic hygiene and well-being of the residents. I am extremely dissatisfied with the living conditions in our building and cannot recommend it to anyone until this issue is addressed in a timely and effective manner. I urge the building management to take immediate action to remove the garbage and eliminate the odor, and also to put in place a more proactive system for garbage collection and disposal to prevent a similar situation from happening in the future.

Hello there, We are unfortunate to read this review but appreciate the feedback as always. Please contact the leasing office and ask to speak to one of our managers and we’d be more than happy to address and discuss the following with you as soon as possible!
We recently moved in to OSLU and love it! Joey was our leasing agent and was super helpful, knowledgeable and professional. He made the moving process a breeze! He gave us multiple tours of different units and floor plans until we found the one that was perfect for what we were looking for. Thanks, Joey! :)
From my touring the property as a prospective resident to my getting settled in as a resident, everyone I have met here has been so kind and helpful. In particular, Hans in leasing was very friendly and knowledgeable, and he went above and beyond to help me find an apartment I would love living in. The building is beautiful with great amenities, and it is in a great, walkable location. I highly recommend considering Onni South Lake Union!
The Onni SLU team are incredible - truly at a loss for words. What sets it apart: - Aby in Leasing provided a detailed virtual tour, an abundance of photos, videos, and measurements. - For 4 weeks, Aby was so thoughtful and updated on open amenities, all my dog questions (most dog friendly community!) and continued to provide videos/photos whenever I asked! - Amazing Welcome Packet provided, thorough and beautiful detail before moving in. - An Onni Rewards program for all residents to enjoy discounts at local businesses! - Niambi in Resident Services went above and beyond to make us feel at home. Thank you so much, Niambi for showing us such warmth and kindness - like nothing we’ve ever experienced before! - Niambi and Sara are extremely professional, knowledgeable about the building, Onni, Greater Seattle and attentive to your interests or any concerns. I can go on and on with praises - the Onni SLU team is like no other and although the building is spectacular, the people here are what makes it home. Thank you so much again Aby, Niambi and Sara (and Francis!) for all you do. Sign a lease today while there’s still openings!
My experience from application to move-in to resident was seamless thanks to Sarah! She was extremely professional, kind, and happy to help with all my resident needs and inquiries. I highly recommend working with Sarah if you are a prospective or current resident. Also the property itself is beautiful with a lot of amenities and in a great location.
My total experience was seamless thanks to Joey! He was extremely professional, but not snobby. My entire process was done virtually, Joey was informative and very patient! If anyone is interested in this property I would definitely recommend using Joey. Also the property itself is beautiful with a lot of amenities and in a great location.

Our team strives to deliver an excellent experience, and are glad you found this to be the case during your leasing experience with Joey. If you have further needs or questions, please reach out!
The process to apply and move was simple, clear and very quick. As we were moving from out of state, with two young kids and a dog, we were so thankful to have this part of the big move be as smooth as it was. We worked with Joey and his colleagues and they were very responsive and thoughtful. Couldn't be happier and excited to live in this beautiful building!
