Description
Perfectly blending timeless pre-war elegance with an exquisite renovation, residence 6C is a stunning three-bedroom, two-bathroom home that has been thoughtfully reimagined with exceptional craftsmanship and attention to detail. Enter into the gracious foyer where beautiful hardwood floors, soaring ceilings, elegant moldings, and custom millwork immediately set the tone for this sophisticated residence. The expansive living and dining room is bathed in natural western light, creating a warm and inviting space that is equally suited for everyday living and effortless entertaining. The beautifully renovated, windowed kitchen is a true centerpiece of the home, featuring custom cabinetry, premium stainless steel appliances, abundant counter space, and exceptional storage. Designed with both beauty and functionality in mind, it offers an ideal setting for everything from casual mornings to elegant dinner parties. Thoughtfully separated from the entertaining spaces, the private bedroom wing offers three generously proportioned bedrooms with southern and northern exposures. The serene primary suite serves as a peaceful retreat, complete with custom outfitted closets and an en-suite windowed bathroom. Two additional spacious bedrooms offer excellent closet space and share an equally well-appointed second full bathroom. Additional highlights include hardwood flooring throughout, custom closets, three exposures, through the wall AC, built in speakers, and storage unit that transfers with the residence. The special home seamlessly combines the character and scale of classic pre-war architecture with the comfort, style, and convenience of modern luxury. Originally designed by the renowned architectural firm Warren & Wetmore in 1923 as the Trafalgar Hospital, Trafalgar Court was thoughtfully converted into an intimate cooperative in 1980. This boutique, pet-friendly building consists of just 27 residences and offers a beautifully landscaped courtyard with a grill, complimentary laundry room, bicycle storage, children's playroom/party room, renovated lobby, video intercom system, and a live-in super. Perfectly situated in the heart of Carnegie Hill, just moments from Central Park, Museum Mile, outstanding restaurants, shopping, top schools, and convenient transportation, Trafalgar Court offers an exceptional lifestyle in one of Manhattan's most coveted neighborhoods. Pied-à-terre ownership is permitted. Flip tax - $150 per share paid by the seller.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
