Welcome to Penthouse C at 333 East 68th Street, a rare opportunity to own a true townhouse in the sky. Spanning approximately 5,500 square feet across three floors, with an additional 1,600 square feet of private outdoor space, this expansive 14-room residence includes six to seven bedrooms and seven-and-a-half bathrooms, all within a premier full-service pre-war cooperative. Located on a quiet, tree-lined block in the heart of the Upper East Side, this home combines the space and layout of a private townhouse with the convenience of a white-glove building. A semi-private elevator opens to a gracious foyer and elegant staircase, leading to a grand corner living room with restored wood paneling, a wood-burning fireplace, and oversized windows with open eastern and southern exposures. The formal dining room comfortably seats twelve, while the renovated chef's kitchen features a Wolf six-burner vented range, double ovens, two sinks, a large stone island, and ample storage. A spacious family room, ideal for casual living and entertaining, and a windowed powder room complete the main floor. Upstairs, the primary suite includes two windowed en-suite baths, a fireplace, and a custom dressing room. Two additional bedrooms with en-suite baths, a study or fourth bedroom, a reading nook, and a recreation space round out the second floor. The penthouse level features a dramatic great room with floor-to-ceiling windows, a fireplace, and access to a spectacular 1,600-square-foot terrace with open city views-perfect for entertaining, dining, or gardening. This floor also offers two more bedrooms with en-suite baths, a hidden library accessed through a bookshelf passage, a staff room with bath, and a large windowed laundry and utility room. Both passenger and service elevators serve this level. Additional features include hardwood floors throughout, built-in sound systems, generous storage, through-wall A/C on the lower levels, and central A/C on the top floor. Built in 1928, 333 East 68th Street is a prestigious cooperative with 24-hour doormen, a live-in resident manager, and only two homes per landing. Amenities include a landscaped garden, gym, laundry room, bike storage, and two private storage rooms. The building permits 65% financing, is pet-friendly, and has a 2% flip tax paid by the buyer. This is a rare and remarkable offering-an elegant, house-like home with light, space, and luxury, in one of Manhattan's most coveted neighborhoods.
