Sponsor Unit! No board approval - move right in! Sunlight pours into this beautifully renovated one-bedroom just off Park Avenue - a rare Upper East Side find under $500K that truly has it all. Completely gut-renovated and move-in ready, this charming home blends modern finishes with classic prewar character. The bright living room features two exposures, oversized windows, and high ceilings, creating an airy, welcoming feel throughout. The windowed kitchen is thoughtfully designed with sleek cabinetry, a dishwasher, and the convenience of an in-unit washer/dryer. Tucked away in the rear, the queen-sized bedroom is pin-drop quiet with double exposures, offering both privacy and natural light. Located at 120 East 83rd Street, a well-maintained prewar elevator co-op in the heart of the Upper East Side, residents enjoy an intercom system, central laundry, and bike storage. (Cats permitted; sorry, no dogs.) Positioned in one of the most sought-after pockets of the neighborhood, you're two doors from the iconic Lexington Candy Shop, moments from The Mark Hotel, Bemelmans Bar, The Surrey, and Casa Tua, along with the boutiques of Madison Avenue and convenient access to the 4/5/6 and Q trains. Apartment 4B is the perfect opportunity to own a turnkey home in an unbeatable location - a true Upper East Side gem. Please note that some images have been virtually staged.
