Own a true Harlem duplex where architectural charm meets buyer value. This beautifully maintained one-bedroom duplex at The Washington Co-ops offers a rare blend of architectural character, comfortable scale, and smart long-term value. The main level opens into a bright, airy living and dining space where hardwood floors and generous ceiling height create an immediate sense of openness. The kitchen is both stylish and functional, featuring crisp white cabinetry, a warm brick backsplash, granite countertops, and stainless-steel appliances - an effortless setting for both everyday living and easy entertaining. A sculptural spiral staircase serves as the home's architectural centerpiece, leading to the private upper-level bedroom. Thoughtfully sized with excellent closet storage, the space offers a calm and comfortable retreat from the pace of the city. The updated bath completes the home with warm wood tones and clean, modern finishes. The Washington is a well-maintained, pet-friendly HDC co-op in vibrant Hamilton Heights. Residents enjoy a thoughtfully curated set of amenities including a fitness center, bike storage, community room, playroom, additional storage, and two central laundry rooms. A key-access courtyard garden with barbecue area provides a welcome outdoor escape, while garage parking is conveniently located just across the street. Subletting is permitted after two years of residency (board approval required), and there is no flip tax. With monthly maintenance lower than many nearby buildings, strong fundamentals, and convenient access to the A/B/C/D and 3 trains, this home presents a compelling opportunity for buyers ready to make a confident first step into ownership in one of Upper Manhattan's most dynamic neighborhoods.
