Nestled along the Charles River, Cambridge is home to both Harvard University and the Massachusetts Institute of Technology, two world-class universities that are located just two miles from one another. This one-of-a-kind college town stands as a historical, cultural, and education hub for the state of Massachusetts. Cambridge offers a charming atmosphere and unbeatable proximity to big-city living with its central location in the Boston metro area, located just three miles west of Downtown Boston.
Nicknamed the “City of Squares” for its intersecting commercial districts, Cambridge offers residents direct access to urban amenities. Kendall Square can be compared to Silicon Valley due to its continuously growing concentration of start-ups. Central Square is your go-to for international restaurants, and Inman Square is a top pick for shopping, cafes, and nightlife. Art is alive and well in Cambridge, between street murals and sculptures and art galleries dotting the city streets.

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 Flats on First
The apartments are modern and well-designed, if a bit small and short on storage space, and the appliances are way nicer than what you'd find in a normal apartment building in Boston. However, there is absolutely no insulation between floors. You will hear every step your upstairs neighbor takes, and each one will sound like a 20-lb weight being dropped on the floor. It's a shame because the building is otherwise very peaceful, and the neighborhood is really a nice place to live. Update: After four months of living here, I have to take off a star due to issues with the building services and the finishings in the unit. Just too many problems for what this place charges in rent. As far as the building goes: 1) There's not a package room as is advertised on the website, and the package lockers have been down since late September, with no indication as to when they will be fixed. The building management blames the vendor, but they also haven't found any other solution to the problem. They just scatter everyone's packages all over the floor of the mail area, unsecured, and don't send any notifications when you receive something. 2) The after-hours maintenance staff isn't responsive. There's not a number to call if you have an after-hours maintenance issue; you just have to submit a request through the resident app and hope someone sees it. I had a lock-out issue once, and, after waiting a half-hour for a maintenance person to arrive and then another 40 minutes for the person to try to unlock my door, I finally just went and stayed in a hotel for the night. As far as the units, the main window in my apartment is without window treatment of any kind. Management said something about them either ordering or receiving the wrong kind of blinds for that window and then told me I could provide the window treatment on my own. Not OK for what this place charges. Update #2: I can now echo one of the other reviews here. I've had packages go missing as well. Contrary to what the website says, there is no "24-hour package room". Management just lets packages be scattered all over the floors by the mailboxes, unsecured and unorganized. Not even a basic level of competence on display here.

The facilities are all very nice and new but the noise isolation isn't up to par. I can hear upstairs stomping, showering, running taps etc. Just moved in and it's already getting on my nerves
