From the original listing · Realtor.comShow

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 marblestyle 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.
