This gracious, light-filled duplex offers beautifully proportioned rooms and sweeping views over the Frick Collection and Central Park from its major rooms. Located just off Fifth Avenue at 3 East 71st Street, the residence combines classic elegance with exceptional livability. The main level features an inviting entry, a formal dining room adjoining the kitchen, an open library to the living room, and one of two wood-burning fireplaces. A gracefully curved staircase leads to the private bedroom level. The primary bedroom suite is exceptionally large, with two generous closets and the second fireplace. Thanks to the thoughtful configuration of the duplex layout, the primary bathroom is unusually spacious for a building of this vintage-providing a level of comfort and storage rarely found in post-war construction. Each additional bedroom has its own en-suite bath. A rare convenience, each floor has its own service entrance providing access to the service elevator and common hallway, making daily living - from deliveries to luggage - remarkably easy without relying on the interior staircase. Additional highlights include a powder room, a separate office on the first level, abundant closets, a full-size washer and vented dryer, and a windowed area by the laundry measuring approximately 14'10" x 7'1" - ideal as a second home office, exercise space, creative studio, or space that can be incorporated into the third bedroom. The building also offers private storage and a resident gym. Thoughtfully maintained and in excellent condition, this home offers a rare opportunity to enjoy space, light, views, and timeless architecture in one of the Upper East Side's most refined locations.
