This mansion was designed by C.P.H. Gilbert and is now home to 13 Luxurious apts in an ultra private setting. Apartment 4/5C is a loft-style duplex condominium with 3 Bedrooms, and 2 bathrooms (with room for additional baths). The sprawling 2050 sq. ft. (per draftsperson) home enjoys a large corner primary bedroom with an en-suite expanded bathroom. The separate formal dining room and spacious living room are perfect for entertaining. Enormous west-facing windows combined with an 11 Foot ceiling height offer an abundance of natural light that flows throughout the apartment. A well-appointed chef's kitchen on the upper level plus an additional kitchen/pantry on the lower level make cooking and entertaining at home a pleasure. Two wood-burning fireplaces, beautiful hardwood floors, and custom built-in pearwood cabinetry finishes throughout. Apt 4/5C has both south and west facing exposures with open city skylines and peaks of Central Park. Outfitted with a full size separate laundry room, ample walk-in closets, and additional storage areas, the duplex has all the space you need and more. Built in 1910, the Condominium has a part-time super, secure virtual doorman service, and a managing agent. The world-class location is on a tree lined Park block, close to Museum Mile, Fifth Avenue Shopping, and Madison Avenue Dining. Pet-friendly.
