520 East 86th Street, 4C: the prewar architectural dream of Vincent Astor and Charles Platt. Full service living in a boutique prewar building that is private, quiet and stately. The semi private landing leads to nine gracious rooms. A LR with working fireplace (the building supplies the wood) and a formal windowed DR are separated by a corridor from three bedrooms, a staff room and three baths. The library could serve as a fourth bedroom. The heart of the home is the Smallbone designer kitchen with a full eat-in breakfast area. There is a full washer-dryer in the kitchen, as well as a building laundry room. Closets are ample/refitted for maximum appeal, and a storage unit in the basement conveys with the apartment. The well-equipped work out room and bike room complete the amenities. Live-in Superintendent and full Staff. No flip tax. Pets welcomed. Start your day by pushing the "Taxi" button in the elevator, and your ride will await you on the street. Nearby: the Second Avenue Subway and Carl Schurz Park with gardens, playgrounds, dog parks and an esplanade on the East River.
