Designed in 1925 by noted residential architect J. E. R. Carpenter, 610 Park Avenue began life as Mayfair House, a 450-room hotel and onetime home of the famed Le Cirque restaurant. Developer Donald Trump and partners bought the building in 1998, and, after a complete renovation, it was converted to 70 condominium apartments. A modest-yet-elegant lobby and luxurious interiors with pre-war finishes like coffered 9-foot ceilings, seven-inch base moldings, fireplaces, libraries and spacious living rooms make The Mayfair a standout. Amenities include a full-time doorman, a fitness center, valet parking, laundry facilities and storage space. A prime Lenox Hill/Upper East Side location puts residents within easy walking distance of Central Park as well as Madison Avenue shopping and restaurants. A bonus for foodies: One of the city's top restaurants, Daniel, is located in the building.
