This elegant floor-through residence offers three bedrooms and three-and-a-half bathrooms, with both north and south exposures that bathe the home in natural light. Soaring 10-foot ceilings, beautifully restored oversized mahogany windows, and white oak flooring in a combination of chevron and plank patterns lend the interiors a sense of timeless sophistication. A gracious entry foyer and gallery lead to a spectacular great room designed for both everyday living and entertaining. Beyond, the custom Molteni kitchen combines exceptional craftsmanship with modern functionality, featuring Calacatta Gold marble countertops and backsplash, cerused oak cabinetry, and top-of-the-line Gaggenau appliances, complemented by a 45-bottle Sub-Zero wine refrigerator. The serene primary suite overlooks the quiet courtyard and features generous closet space and a luxurious, windowed spa-style bathroom. Clad in striking Siberian white slab marble, the bath is appointed with radiant heated floors, a deep soaking tub, and custom vanities with fixtures by Kohler, Dornbracht, and Kallista, creating a private retreat within the home. Two additional bedrooms each feature beautifully appointed en-suite bathrooms finished in Grigio Nicola stone, with radiant heated floors and custom Molteni-designed vanities. Off the gallery, a distinctive powder room is finished in polished Nero Marquina marble and features a sculptural Snow White marble sink. Additional conveniences include a Whirlpool washer and dryer, high-performance VRF dedicated HVAC, and integrated Intrahome technology infrastructure. Blending classic pre-war elegance with contemporary luxury, the residence is complemented by an extraordinary collection of amenities spanning more than 30,000 square feet indoors and out. Residents enjoy a 24-hour attended lobby, grand porte-cochère, and a beautifully landscaped 22,000-square-foot courtyard and garden offering a rare sense of privacy and tranquility.
