Property Description
Just one block from Central Park on one of the Upper West Side's most desirable tree-lined streets, this sun-filled and grand scale, renovated 7-room duplex seamlessly combines sophisticated design, modern luxuries, and exceptional functionality. Bathed in natural light through oversized west-facing windows, this expansive home enjoys open city views and a thoughtfully designed layout offering 3 to 4 bedrooms and 3 beautifully renovated full bathrooms. Throughout the residence, special features include nearly 10' high ceilings, multi-zone central air conditioning, a built-in speaker system, top-of-line appliances, hardwood floors, custom pocket doors, and an extraordinary abundance of custom-fitted closets and storage. A dramatic custom staircase, highlighted by integrated lighting and open bookshelves, leads to the private lower-level primary suite, a tranquil retreat designed for ultimate comfort. Spacious enough to accommodate a separate den, media lounge, or home office, the suite is exceptionally quiet thanks to double-paned windows that showcase open city views. The luxurious spa-like primary bath is finished in marble with mosaic tile floors, a double vanity, a freestanding deep soaking tub, a seamless glass shower, and ultra-premium DXV American Standard fixtures. Completing this exceptional suite is a remarkable custom dressing room with extensive built-in storage. The upper level is perfectly designed for both entertaining and everyday living, featuring a loft-like expanse with an open living room, formal dining room, and chef's kitchen. Anchored by a large center island with breakfast bar seating, the kitchen is appointed with abundant custom cabinetry, stone countertops, two sinks, two Bosch dishwashers, a vented Bertazzoni gas range oven, and a built-in microwave. A beautifully renovated full bath is conveniently located off the entertaining space for guests. Privately tucked away from the main living areas, the quiet bedroom wing offers three bedrooms, one currently configured as a home office, and an additional renovated full bathroom. Ideally located moments from Central Park, the Museum of Natural History, excellent dining, shopping, and transportation options, Apartment 6KL is a rare opportunity to enjoy gracious duplex living with every modern convenience in the heart of the Upper West Side. 51 West 81st Street, also known as The Galaxy, is an elegant prewar co-op in the heart of the Upper West Side. The Beaux-Arts building was constructed in 1903 and converted to co-op in 1979. The accommodating staff includes a doorman and resident manager. Amenities include a landscaped roof deck with multiple seating areas and panoramic city skyline and Park views, laundry on every floor, and bicycle storage. Elevators, hallways and laundry areas have all been recently updated. Pets permitted.
