A Rare Triple-Mint in Rosario Candela Condominium on Madison Avenue with Interiors by Jennifer Cohler Mason

Perched on a high floor of a coveted white-glove pre-war condominium, Residence 12B at 40 East 66th Street is an extraordinary 6-bedroom, 6.5-bathroom home offering nearly 5,000 square feet of impeccably designed living space. Originally crafted by legendary architect Rosario Candela and reimagined by acclaimed designer Jennifer Cohler Mason, this rare corner residence perfectly marries timeless elegance with modern luxury.

Enter through a private elevator landing into a sun-filled home with north, south, and west exposures that frame open views of Central Park, the city skyline, and iconic Upper East Side architecture. The expansive living room features dual seating areas, a wood-burning fireplace, and oversized windows overlooking Madison Avenue. A stately corner library with custom millwork and views down 66th Street adds to the home's refined charm.

The formal dining room is anchored by a fireplace and detailed mantle—ideal for grand entertaining—while the adjacent chef’s kitchen is outfitted with Wolf, Miele, and Sub-Zero appliances, an oversized island with seating, and a spacious butler’s pantry. A generous den flows off the kitchen, creating a seamless space for casual living. A separate wing houses the sixth bedroom, full laundry, and additional storage.

The luxurious primary suite includes a second wood-burning fireplace, a vast custom dressing room, and a spa-quality marble bath with dual vanities, radiant heated floors, and top-tier fixtures. Each of the five additional bedrooms features its own en-suite marble bathroom, ensuring comfort and privacy throughout.

Notable finishes include herringbone hardwood and marble flooring, central air conditioning, custom millwork, and a Sonos sound system throughout.

Located in one of the Upper East Side’s most distinguished condominiums, 40 East 66th Street offers 24-hour doorman and concierge service, a fitness center, children’s playroom, bike room, and is just one block from Central Park and steps from Madison Avenue’s finest dining, shopping, and cultural destinations.
