450 E 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. With over 1, 200 square feet, soaring 11-foot ceilings, and massive east-facing windows that flood the home with natural light, this residence offers space, flexibility, and understated luxury. The oversized bonus room-with the same ceiling height and generous proportions as the rest of the apartment-easily functions as a den, home office, guest room, or additional sleeping space, making the layout as versatile as it is elegant. The expansive living room is bright and airy, flowing seamlessly from a gracious entry gallery. The chef's kitchen is outfitted with top-of-the-line appliances, including a Wolf cooktop and wall ovens, Sub-Zero refrigerator, Miele dishwasher, and a rare garbage disposal. The king-sized primary suite features a large walk-in closet and a serene en-suite bath with soaking tub and separate glass shower. 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.
