Description

This is the apartment you keep in New York. Not a compromise. Not a project. A fully gut-renovated, 1,860-square-foot residence on one of the most storied addresses in the city, ready to walk into and immediately feel at home. The renovation is exceptional. Marble, custom millwork, wide plank European white oak floors throughout - nothing was an afterthought. Southern and northern exposures keep the home bright all day, with views over the historic townhouses of Lenox Hill. The kitchen opens into a gracious entertaining sequence: a wine bar, generous living and dining room, and a library and den that give the space unexpected depth. The kitchen itself is serious: Wolf range, Wolf speed oven, Subzero refrigerator, and Miele dishwasher. The primary suite has two walk-in closets and a marble bath with Thassos mosaic, Calacatta Vaglia stone, Fantini fixtures, and Murano glass handles. Three fully renovated baths in total. Laundry, storage and mud room off the foyer. 650 Park is white-glove in every sense: 24-hour concierge, fitness center, parking garage, rooftop terrace with city views, and recently renovated common areas throughout. Pied-à-terres and pets welcome. Central Park, the Park Avenue Armory, Plaza Athénée, The Lowell, private clubs, and Michelin-starred restaurants are all within a few blocks. This is the Upper East Side at its best, with nothing left to do but enjoy it. All utilities including electricity are included in the monthly maintenance. Two percent flip tax paid by purchaser. There is an ongoing assessment of $619 per month. Please inquire for private showings, Monday to Friday only.
