Lovingly cared for by the current owner for over two decades, the home has been impeccably preserved and lightly lived in. Designed with a townhouse-like layout, the first floor is devoted to entertaining and open living, while the upper level houses the private bedroom wing. The gracious living room seamlessly connects to an oversized terrace, creating a true indoor-outdoor experience high above the city. Adjacent to the living space, the formal dining area is equally impressive and opens onto its own private terrace, perfect for morning coffee, sunset dining, or entertaining against dramatic skyline backdrops. Great ceiling heights and oversized windows throughout enhance the scale and light of every room. The windowed kitchen is thoughtfully positioned alongside the dining area and features generous storage, extensive workspace, and an ideal layout for both everyday living and entertaining. A powder room, abundant closets, and a welcoming foyer complete the lower level. Upstairs, the private primary suite enjoys its own secluded terrace overlooking the city and river, offering a peaceful retreat rarely found in condominium living. The suite is complemented by substantial closet space and an en suite bath. The second bedroom is generously proportioned and enjoys open views and excellent natural light. Both bedrooms benefit from the privacy and quiet separation of the upper floor. With three large private terraces off the living room, dining room, and primary suite, this remarkable residence offers an extraordinary amount of outdoor space rarely available in the sky. Combined with incredible sunlight, dramatic views, and an ideal duplex layout, the apartment delivers a truly elevated Upper East Side living experience. The Kingsley is a full service white glove condominium offering a full time doorman, concierge, live-in superintendent, fitness center with city views, bike room, storage, and on-site garage with direct building access. Ideally located on the Upper East Side near excellent restaurants, shopping, transportation, and the Second Avenue Q train, this exceptional home combines privacy, scale, and luxury living in one of Manhattan's most established condominium buildings.
