450 East 83rd Street 4-H Welcome to this sprawling, mint-condition 1-bedroom PLUS large bonus room, that lives like a 2-bedroom, at the Cielo Condominium.

A second full bath beautifully finished in stone and tile with a glass shower and vessel sink adds both style and functionality. Additional highlights include rich hardwood floors, a full-size washer/dryer, and generous storage throughout. Set within The Cielo, a premier white-glove condominium offering 24/7 lobby attendant, concierge, fitness center, children s playroom, and on-site garage with direct residential access, this elegant offering combines exceptional space and value just moments from the beautiful Carl Schurz Park (with its pickleball courts & dog run), Asphalt Green sports complex, and the East River Promenade. It s a true embodiment of Upper East Side living in the heart of vibrant Yorkville.
