Introducing a classic 6 in the heart of the Upper East Side. Set on the tenth floor of a full-service, white-glove prewar cooperative, Apartment 10D is accessed via a private double-door elevator landing and enjoys open eastern views with beautiful natural light throughout the day. The apartment offers classic prewar charm, with original hardwood floors, generous proportions, and a layout that feels both comfortable and welcoming. The living and dining areas are well sized and lend themselves easily to everyday living as well as entertaining. The windowed kitchen includes the rare convenience of an in-unit washer and dryer. The bathroom retains its original cast-iron tub and vintage finishes-thoughtful details that add character and a sense of history to the home. 1105 Park Avenue is a well-established, full-service building with attentive staff, ideally located just moments from Central Park, Museum Mile, and some of the Upper East Side's most beloved restaurants, shops, and transportation. Apartment 10D is a special opportunity to own a classic Park Avenue prewar residence with light, warmth, and enduring appeal in one of Manhattan's most desirable neighborhoods.
