We go inside the former home of 'ol blue eyes Frank Sinatra. This storied penthouse features 3,000 square feet, four bedrooms, 18-foot ceilings, views of the East River, wraparound terrace, a glass spiral staircase, and a putting green. It's not wordier this space was dubbed the "glittering grotto in the sky" by Andy Warhol. For more information on this property, please contact Jason Haber at 212-203-9561. View the listing.
