Description

Located at The Carlton House, inspired by the finest elements of Art Deco and Moderne design, this residence embodies elegance, exceptional craftsmanship, and refined aesthetic integrity. This exquisite two-bedroom, two-and-a-half-bath home pairs generous proportions with a sophisticated, understated design in a prime Upper East Side location between Central Park and Madison Avenue. Set within one of Manhattan’s most established residential enclaves, the residence offers immediate access to Central Park, world-class shopping, renowned dining, and the cultural institutions that define the neighborhood. A gracious entry foyer leads into a spacious great room with ample space for both living and dining. Large windows flood the home with natural light and offer open city views, while dark-stained floors and clean, modern finishes create a warm and inviting atmosphere. The open kitchen flows seamlessly into the living area and is designed for both everyday living and entertaining, featuring dark wood cabinetry, white stone countertops and backsplash, a large island with seating for six, integrated storage, a gas cooktop with a vented hood, and built-in wall ovens. A powder room and in-unit washer/dryer add everyday convenience. The primary suite is privately situated and generously scaled, complete with a large walk-in closet and a beautifully appointed en-suite bath with a double vanity, soaking tub, separate glass-enclosed shower, and excellent storage. The second bedroom is also well-proportioned and features its own full bath, ideal for guests, family, or a home office. An additional powder room enhances functionality for visitors. Originally reimagined by Extell Development Company, The Carlton House seamlessly blends classic Upper East Side architecture with modern residential living. Perfectly positioned on East 61st Street at Madison Avenue, the building is surrounded by celebrated boutiques, restaurants, luxury hotels, and galleries, while remaining just moments from Central Park and the Plaza District.
