This "best of both worlds" residence, built in 1966 and converted to a cooperative in 1979, consists of a red-brick Georgian-style low-rise building and a 27-story beige-brick tower. The tower's unique and impressive entrance???through the low-rise building on 72nd Street???leads through a large, elegant lobby and a glass-enclosed walkway flanked by lush gardens before arriving at the tower's elevators. Amenities at this pet- and pied-a-terre-friendly co-op include a full-time doorman, concierge service, a full-service garage, gym, bike room and a garden. This prime Upper East Side location on a classic tree-lined street puts residents steps from Central Park as well as museums, the fashionable shops of Madison Avenue, popular restaurants and all that this highly desirable neighborhood has to offer.
