Description

11 ft ceilings & 14 windows at Madison Ave/78th Street! Welcome to Residence 3BC, an impressively scaled and remarkably spacious two-bedroom, two-bathroom home in one of the Upper East Side’s most charming pre-war cooperative buildings. Ideally situated on a tree-lined block between Madison and Park Avenues, this elegant residence offers a perfect blend of old-world character and modern livability—just moments from Central Park and The Metropolitan Museum of Art.?? High ceilings, hardwood floors, and classic pre-war details define the home where possibilities are limitless. Its thoughtful layout provides ideal separation between the living and sleeping areas.The expansive great room measures an impressive 28 × 18 feet, with each half connected by two beautifully crafted doorways of exceptional quality. Sunlight floods the residence through windows in every room, enhancing the home’s inviting and airy ambiance. There are?14 windows with three exposures - East, West and North, yielding peaceful views of treetops & historic townhouses. Both bedrooms are generously scaled and enjoy excellent closet space. Built in 1893, 51 East 78th Street is an elegant and well-maintained pre-war elevator cooperative offering the privacy of a small building and the charm of European-style living. This intimate five-story building, with two to four residences per floor, features a laundry room, and bicycle storage. Nestled in the heart of the Upper East Side’s Gold Coast, residents enjoy proximity to world-class restaurants such as Kappo Masa and Sant Ambroeus, iconic hotels including The Carlyle and The Mark, and premier Madison Avenue boutiques and galleries. The new elevator project was completed in September 2025. This is a non-smoking building. Sorry, pets are not permitted. 3BC are currently two separate one bedroom apartments with a single owner. They have been beautifully connected and can easily be officially combined, as have other apartments in the building.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, 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.
