This iconic pre-war boutique condominium on Madison Square Park is widely regarded as one of the most coveted addresses on Fifth Avenue. Originally built in 1912, the magnificent building was thoughtfully converted into just 48 exceptional residences, blending historic grandeur with modern luxury. This residence showcases stunning pre-war details, including original dramatic 8-foot high windows and soaring 9-foot to 11-foot coffered ceilings. These architectural elements are beautifully complemented by elegant contemporary finishes and chevron-pattern oak hardwood floors. The Calacatta marble breakfast island and countertops anchor the open chef's kitchen, outfitted with top-of-the-line Gaggenau appliances, custom ash millwork cabinetry and a wine refrigerator creating an expansive great room, reminiscent of a classic downtown loft. Two generously proportioned bedrooms each feature in-suite bathrooms, offering privacy and comfort. The primary bath is luxuriously appointed with double sinks, radiant heated Thasos marble floors, and honed, polished, and fluted marble finishes. Waterworks fixtures enhance all bathrooms, and a discreetly located guest powder room sits just off the entry foyer along with a generous laundry closet with an oversized Bosch washer and dryer. The home is further enhanced by custom automated window shades, integrated lighting, and individual climate controls in every room. This rarely available C-line residence is in mint, move-in condition. Residents enjoy full-service living with a 24-hour doorman, concierge, live-in building manager, state-of-the-art fitness center, game room, and residents' lounge - offering a seamless blend of luxury, service, and convenience in one of Manhattan's most well-known and desirable locations.
