Welcome to Residence 3B at 403 East 87th Street, a distinctive multi-level one-bedroom offering a sense of space and separation rarely found at this price point on the Upper East Side. This thoughtfully designed home features three distinct living areas. The main level includes a spacious eat-in kitchen and an updated bathroom. Upstairs, the private bedroom comfortably accommodates a king-sized bed and offers generous closet space, abundant natural light, and peaceful tree-lined views. The bright and versatile lower level provides plenty of room to relax, entertain, and create a dedicated work-from-home area. This pet-friendly cooperative features an elevator and on-site laundry. Guarantors and co-purchasing are permitted. The building also offers exceptional flexibility for a Manhattan co-op: shareholders may sublet after two years of primary residence, with no limit on future subletting. Ideally located near Whole Foods, Fairway, the Q and 4/5/6 subway lines, Central Park, and Carl Schurz Park, with some of the neighborhood’s best dining, shopping, and conveniences just outside your door. Residence 3B is not your typical one-bedroom. Its unique multi-level layout, generous proportions, and flexible ownership policies make it a rare Upper East Side opportunity.
