Description

Rarely does a three-bedroom home combine such exceptional light, quiet, and privacy. Beautifully renovated and offering three exposures, this inviting residence at Trafalgar Court features a loft-like living, dining, and kitchen area, complemented by a separate bedroom wing for an ideal sense of privacy and separation. The gracious living and dining areas are flooded with natural light through a dramatic west-facing picture window, creating a welcoming space for both everyday living and entertaining. The living area flows seamlessly into a renovated, open windowed kitchen featuring quartz countertops, top-of-the-line stainless steel appliances, custom cabinetry, and generous pantry storage. Privately separated from the entertaining spaces, the bedroom wing includes a large east-facing primary bedroom with a wall of closets and an en-suite marble bath. The spacious second bedroom enjoys a coveted northwest corner exposure, while the third bedroom offers exceptional flexibility as a bedroom, guest room, or home office. A second full bath is conveniently located in the hallway. Additional highlights of this special apartment include beautiful oak floors, built-in bookcases, abundant closet space, through-the-wall air conditioning, and classic prewar details. Trafalgar Court is an impeccably maintained boutique cooperative in the heart of Carnegie Hill, surrounded by tree-lined streets and close to some of Manhattan's finest, museums, restaurants, shops, and parks. The building's lobby, hallways, and elevator have been beautifully renovated, and residents enjoy an impressive array of amenities, including a live-in superintendent, virtual doorman, private landscaped garden with grill, laundry room, playroom, bike storage, and private storage cage. The superintendent is conveniently located on the ground floor and available to accept packages. The building is pet-friendly, and up to 75% financing is permitted. There is a $150-per-share flip tax and a current assessment of $1,198.96 through the end of February 2027.
