Description
Thoughtfully renovated and move-in ready, this two-bedroom, two-bath residence at The Diamond House, 170 East 77th Street, pairs classic character with modern finishes in the heart of the Upper East Side. An inviting entryway opens to a spacious foyer overlooking the gracious step-down living room, offering flexibility as a formal dining area, home office, or play space. Beamed ceilings, crown molding, custom cove and recessed lighting, and hardwood floors give the space a warm, polished feel. A broad living room window brings in natural light, while the distinct levels create a natural separation between work, relaxation, and entertaining. The windowed kitchen features warm wood cabinetry, Carrara marble–style quartz countertops and backsplash, Sub-Zero refrigerator, wine cooler, a GE Profile range and microwave, new Bosch dishwasher, and an LG washer/dryer combo unit. The spacious primary bedroom comfortably accommodates a king-size bed and features a beautiful corner bay window, and a windowed marble bath with a soaking tub, new vanity, and updated fixtures. The queen-size second bedroom includes an outfitted closet, with an adjacent bath offering a glass-enclosed shower, vanity, and updated fixtures. A separately deeded basement storage unit transfers with the apartment. The Diamond House, a 1940s condominium, offers a 24-hour doorman, live-in resident manager, gym, roof deck, and separate laundry room.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
