Description

Light and Layout. First time on the market in more than 20 years, this sun-flooded and rarely available apartment features 4 bedrooms (or 3 bedrooms + library), 5 bathrooms (with the opportunity to add a powder room) and redefines gracious living. With a flexible layout and well-proportioned rooms, the possibilities for this sprawling, classic ~2,675 square foot apartment are endless. A grand 19-foot entry foyer welcomes you home and serves as the heart of the apartment. An oversized 25-foot living room, off the entrance gallery, is perfect for both casual gatherings or formal entertaining and can be easily combined with the adjacent library/den (currently set up as a 4th bedroom) for even more entertaining space. The large formal dining room is across from the living room and adjacent to the windowed eat-in kitchen which can be expanded into the formal dining room and/or the current staff room -- depending on your needs. The three sizeable bedrooms are set off in a separate wing from the main living spaces. Each bedroom has bright exposures, ample closet space and en-suite bathrooms. The apartment boasts bright and cheerful views to the north, and an expansive southern skyline that includes views of classic Upper East Side townhouses, the nearby Carlyle Hotel and many of midtown's iconic buildings. 40 East 84th Street is a well-established Upper East Side co-op with 24-hour doorman service, Resident Superintendent, Bike Room, Storage and Garage. Located just steps from Central Park, the Metropolitan Museum and all the great schools (both public and private), shops, museums, dining and all major transportation that the Upper East Side is known for. The building allows up to 50% financing and permits pets and “pied-a-terres.” Some of the photos are virtually staged.

The 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.
