Description

Welcome to Residence 8W at 21 East 66th Street, a thoughtfully reimagined home for modern living and effortless entertaining, with charming Lenox Hill views and glimpses of Central Park throughout. A gracious gallery, finished with Bianco Bello marble floors and refined architectural detailing, leads to a sun-filled corner living room anchored by a gas fireplace. The space flows seamlessly into the formal dining room and sleek open kitchen, appointed with rift-sawn oak cabinetry, Bianco Bella marble, and top-of-the-line Sub-Zero and Wolf appliances. A sophisticated butler's bar completes the entertaining space. The residence features two beautifully appointed primary suites, each offering open views and luxurious marble baths. A third room, originally designed as a staff bedroom, has been transformed into a petite guest room or home office with its own spa-like bath. A Giorgio Armani powder room provides an unexpected and distinctive finishing touch. Additional features include wide-plank oak flooring, new Marvin windows, sound insulation throughout, new central air conditioning, a vented washer/dryer, and a private storage unit that transfers with the apartment. 21 East 66th Street is an intimate, full-service prewar condominium comprising just 19 residences. Ideally positioned half a block from Central Park in one of the Upper East Side's most coveted locations, the building is moments from exceptional dining, shopping, cultural institutions, and convenient transportation.
