351 E 51St St

A landmarked condominium conversion completed in 2001, this 19-story, limited-occupancy building blends prewar character with modern full-service living. The facade and public rooms recall classical detailing while interiors feature high ceilings, herringbone and other hardwood floors, crown moldings and marble finishes. Residences range from one- to four-bedroom layouts including lofts, duplexes and penthouses; typical unit attributes include formal foyers, separate dining areas, generous closets and in-unit laundry, with upgraded kitchens, double vanities, soaking tubs and walk-in closets commonly found. Shared amenities are extensive: a staffed 24-hour concierge/doorman, mahogany-paneled lobby with Botticino marble, residents’ library and lounge, fitness center with sauna, conference/media room, gated storage and bicycle room. Building services include valet parking and garage access, live-in superintendent, package/cold storage and optional housekeeping/valet conveniences. Pet- and pied-à-terre–friendly policies increase flexibility for owners. Located in Midtown East/Beekman Place, the address places residents near the East River, UN corridor, parks, dining and transit, offering a quiet, tree-lined neighborhood setting while remaining blocks from Midtown workplaces and cultural destinations.
