Welcome to apartment 5H, a beautifully renovated, light-filled one-bedroom on the 5th floor of a well-run Lenox Hill co-op. Offering the rare combination of prewar charm, modern updates, and truly comfortable proportions, the apartment enjoys southwest and northeast exposures, windows in every room, and beautiful natural light throughout. A spacious living room with custom built-ins and window seats connects naturally to a thoughtfully opened kitchen with island seating for two. 345 East 77th Street is a financially sound, pet-friendly cooperative with a live-in superintendent, elevator, laundry room, bike storage, and private storage. The building also offers exceptional flexibility for a co-op, including pieds-à-terre, co-purchasing, guarantors, parental purchasing, and subletting. Beautifully renovated throughout, the apartment blends clean modern finishes with preserved character. The living room offers excellent proportions, with room for comfortable seating, dining, or a work-from-home area. Newly refinished hardwood floors, skim-coated walls and ceilings, updated lighting, restored picture moldings, and carefully refinished original wood doors add warmth and character throughout. The windowed kitchen was redesigned to feel open and inviting while maintaining separation from the living space. It features custom cabinetry, generous quartz counter space, and a comfortable island seating area. The quiet bedroom overlooks neighboring gardens and trees with northeast exposure and comfortably fits a larger bedroom setup. Three renovated closets offer excellent storage, including custom shelving and thoughtful details throughout the apartment. The windowed bathroom has also been fully renovated and features clean, timeless finishes and a glass shower panel. Perfectly positioned in Lenox Hill near the Second Avenue subway, restaurants, cafes, and neighborhood shopping, apartment 5H offers warmth, functionality, light, and tasteful renovation in one of the Upper East Side's most established locations.
