Wall Street veteran and tech entrepreneur Jonathan Gray has put up his Manhattan co-op for sale.

Located at 333 East 57th Street in mid-town Manhattan, this light-filled, classic nine-room residence features three impressive master bedrooms, a study, four bathrooms and a 27′ living room with wood burning fireplace. The elegant, oversized 27′ Clive Christian kitchen comfortably seats 10 and boasts integrated cabinetry and top-of-the-line appliances, including Sub-Zero refrigerator with matching freezer and wine cooler, Wolf eight-burner range, two Miele dishwashers and convection micro oven, steam oven, coffee maker, warming drawer and washer/dryer.

With a gracious foyer and 22′ dining room with hand-painted murals, the home provides the perfect setting for both formal and casual living. The en-suite bathroom transforms the library into a 4th bedroom and the staff room serves as an office or exercise room. The full-service, pre-war, pet-friendly building has a landscaped garden spanning its width and a roof top terrace.

Jonathan Gray spent thirty years working on Wall Street at Salomon Brothers, Goldman Sachs and J.P. Morgan. Since retiring, he has divided his time between New York City and Florida. His latest venture, an iOS mobile app named CollegeHunch available free in the App Store, transforms college research and helps students and parents make informed college choices. He intends to call Fort Lauderdale his home when the oceanfront development, The Auberge Beach Residences and Spa, is completed in early spring.
