This well-proportioned one-bedroom duplex offers a flexible two-level layout, with the living space on the main level and the bedroom above. The home opens into a long living room, where four large windows bring in steady natural light throughout the day. The proportions are immediately clear, with a length that allows for multiple distinct uses within a single, cohesive space. The living room is notably long, making it an excellent space for entertaining with clearly defined zones-space for lounging, a proper dining area, and a dedicated workspace. If you prefer greater separation, a portion of the room can be enclosed to create a fully separate, windowed home office or guest room. The kitchen is positioned just off the entry and is clean, efficient, and well maintained. It features full-size appliances, with an 18-inch dishwasher, along with ample cabinetry and a straightforward layout that makes it immediately functional while still offering a clear path for future refinement. A comfortable, well-scaled staircase leads to the upper level, with two windows bringing natural light into the stair hall. The bedroom is generously scaled, easily accommodating a king-size bed along with additional furniture. It feels open yet quiet, with good light and a sense of privacy that is often missing in typical one-bedroom apartments. Closet space is well distributed across both levels, supporting practical, everyday living. The bathroom is in solid, well-kept condition, clean and fully functional as it stands, with room for personalization over time. The Washington occupies an imposing row of historic walk-up buildings that were completely reimagined and combined into a single elevator cooperative using financing from the New York City Housing Development Corporation. Purchasers must have a maximum household income of $364,500 (250% of AMI). Financing of up to 90% is permitted. Please note, this is NOT an HDFC co-op. This pet-friendly building is well maintained and offers two elevator banks, two laundry rooms, a fitness room, bike storage, community space, and a live-in superintendent. Monthly maintenance includes heat, hot water, and gas. Positioned in the heart of Harlem, the location offers convenient access to the A, B, C, and D trains at 145th Street, as well as the 3 train at 148th Street-Lenox Terminal, providing fast, direct access to Midtown and Lower Manhattan. Nearby, St. Nicholas Park offers expansive green space along with a popular public pool, while neighborhood standouts include Briciola Harlem, a branch of a well-loved Hell's Kitchen wine bar known for contemporary Italian cooking and thoughtfully selected wines, Benyam Ethiopian Cuisine, a family-run restaurant serving traditional Ethiopian dishes, Common Good Harlem, a neighborhood coffee bar and gathering space, and Charles Pan-Fried Chicken, long considered one of Harlem's defining institutions.
