Description

Sophisticated Living. Unmatched Location. Steps from Central Park. Discover an exceptional combination of elegance, privacy, and premier location in this impeccably renovated 2-bedroom, 2-bath residence at The Carlton House, one of the Upper East Side's most prestigious full-service condominiums. Spanning approximately 1,193 square feet, this triple-mint home features a highly sought-after split-bedroom layout and predominantly eastern exposure, filling the residence with beautiful natural light throughout the day. Thoughtfully positioned away from the street, the home offers remarkable tranquility and privacy-an increasingly rare luxury in the heart of Manhattan. A gracious marble entry gallery welcomes you into an expansive 21-foot great room, where elegant beamed ceilings and oversized casement windows create a refined setting for both entertaining and everyday living. The chef's kitchen is beautifully appointed with stone countertops, custom white lacquer cabinetry, premium Miele appliances, a Sub-Zero wine cooler, a five-burner gas cooktop with a pot filler, and a full-size in-unit Miele washer and dryer. The spacious primary suite enjoys both eastern and southern exposures and features custom-designed closets, including an oversized walk-in closet. The luxurious five-fixture marble bath is appointed with radiant heated floors, dual vanities, a deep soaking tub, and a separate glass-enclosed shower. Privately positioned on the opposite side of the residence, the generously sized second bedroom offers ideal separation for guests, a home office, or family living. A beautifully finished second marble bath completes the home. The Carlton House is an exclusive 68-residence boutique condop offering an exceptional level of service and amenities, including a beautifully attended lobby, 24-hour doorman and concierge service, a state-of-the-art fitness center, a 65-foot indoor heated swimming pool, a steam room, a game room, bicycle storage, private storage, and refrigerated storage. Perfectly situated on Madison Avenue at East 61st Street, just steps from Central Park and moments from Madison Avenue's renowned boutiques, acclaimed restaurants, luxury hotels, and world-class cultural institutions, this move-in-ready residence presents a rare opportunity to own a sophisticated home in one of Manhattan's most coveted neighborhoods.
