Terraced on every side, this elegant ten-room, full-floor home is ideal for grand scale entertaining. The living room, library and master bedroom each have wood-burning fireplaces and tall French doors giving on to the sunny South terrace which overlooks the Park Avenue Armory. A private elevator vestibule leads into the grand, central gallery. The living room, 30 feet long with ceiling heights of almost 11 feet, flows graciously into the formal, corner dining room. The apartment features a double-sized master bedroom, a large second bedroom with a dressing area and two smaller, contiguous rooms which could be a third bedroom. There is also a staff room and wine room. Originally fourteen rooms with three large bedrooms and four staff rooms, there remain many possibilities for configuring the private space. The building affords a discreet, prestigious address with incomparable services. The cooperative allows pets. Pied-a-terre purchase is permitted.
