Description

Welcome to 321 East 43rd Street, a beautifully renovated one-bedroom residence perfectly positioned in the tranquil enclave of Tudor City. This thoughtfully designed home combines classic pre-war character with modern comforts, creating a serene escape in the heart of Midtown East. As you enter, a gracious foyer introduces the home’s inviting proportions and generous storage, including a deep coat closet. The living room is bathed in natural southern light through elegant iron-casement windows, highlighting refinished hardwood floors and high, beamed ceilings that recall the timeless craftsmanship of the building’s 1920s origins. The layout easily accommodates both living and dining areas, offering a flexible, airy flow ideal for entertaining or quiet evenings at home. The windowed kitchen blends style and practicality with sleek cabinetry extending to the ceiling, stone countertops, and a suite of stainless steel appliances, including a Liebherr refrigerator, Bosch dishwasher, and Dacor oven and microwave. The spacious bedroom features two large windows, ample closet space, and direct access to the windowed en-suite bathroom, finished in classic tilework and designed with a second entry for guest convenience. Set within The Cloister, part of the landmarked Tudor City complex designed by Fred F. French, this full-service cooperative offers a 24-hour doorman, concierge, live-in superintendent, laundry facilities, bike storage, and available private storage. Residents also enjoy access to the beautiful Tudor City Greens parks, an urban oasis that hosts concerts, art shows, and community events year-round. Located moments from Grand Central Terminal, the United Nations, NYU Langone, and Midtown’s finest dining and shopping, this home is perfect for those seeking the charm of Old New York with the ease of modern living. Pied-à-terres, co-purchasing, and guarantors are permitted, and pets are welcome. This move-in-ready residence, freshly painted, meticulously maintained, and offered fully furnished with stylish West Elm pieces, presents a rare opportunity to own a turnkey home in one of Manhattan’s most distinctive and peaceful neighborhoods.
