The living area serves as the heart of the unit, featuring warm wood-style laminate flooring and crisp white walls that create a clean, bright aesthetic throughout. A sliding glass door opens directly onto a private balcony, providing outdoor access and allowing natural light to fill the space. A wall-mounted HVAC unit ensures climate control within the living area. The bedroom is a comfortable, defined space with its own window fitted with vertical blinds, offering views of the surrounding exterior and admitting additional natural light. Textured ceilings are present throughout the unit, adding subtle depth to the otherwise minimalist interior. A dedicated closet provides practical storage directly accessible from the living areas. The bathroom features a single-basin vanity with a speckled countertop and a large mirror, maintaining the unit's clean and functional design language. An entrance area provides a clear transition point upon entry. The overall layout, as reflected in the floor plan, flows logically from the entrance through the living space and into the private bedroom and bathroom, making efficient use of every area within the unit.

Just a little over 30 miles east from Downtown Los Angeles, the Bonita neighborhood encompasses the whole northern part of the city of San Dimas and parts of La Verne. The Bonita neighborhood sits at the base of the San Gabriel Mountains, giving residents a beautiful mountain backdrop to enjoy. Being so close to both the mountains and just a quick drive away from Downtown LA, this neighborhood has seen a steady growth through the years. This popular suburb attracts many families due to the Bonita Unified School District which includes 14 schools and serves over 10,000 students. A number of classically LA apartments and a few single-family homes means there’s something for everyone in Bonita.

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.
