An expansive entrance gallery leads to a gracious living room measuring approximately 31 feet, providing an exceptional setting for entertaining. A separate formal dining room complements the generous layout, while classic moldings and parquet floors lend warmth and character throughout. The private bedroom wing includes three spacious bedrooms, each with an en-suite bathroom and oversized closets. A separate guest room with a full bathroom offers flexibility as a fourth bedroom or home office. A windowed kitchen completes the home. New windows and through-the-wall heating and air conditioning with individual room controls provide modern comfort within the building's classic 1949 architecture. A storage unit is included in the sale of 15E with no ongoing storage fees. 870 Fifth Avenue is a white-glove cooperative with an attentive staff and thoughtfully enhanced amenities. The newly completed roof garden features all-new pavers and furnishings, creating a beautiful retreat where residents can relax and enjoy sweeping views of Central Park and the city. An inviting interior garden just off the first-floor lobby features lush trees, shrubs and flowers, crushed-stone paths and café tables where residents can relax. A new meeting room off the lobby can be reserved through the building for private meetings, while a well-equipped fitness center offers everything needed for a convenient workout. The building also has a generator, and Local Law 11 work has been completed. A hallway improvement program is scheduled to begin in 2027, with upgrades to electrical systems, décor and lighting. Central Park is directly across Fifth Avenue, with the Upper East Side's museums, shops and restaurants nearby. The nearby park entrance is at East 67th Street, beside Billy Johnson Playground, known for its granite slide built into the rocks. Pets are allowed under 40 Ibs.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
