Tour the Upper East Side penthouse where Sinatra used to host wild ragers with his Rat Pack
Mitchell - who told The Wall Street Journal that he purchased the home for its spacious floorplan, not its history - takes ownership of the 3,200-square-foot, tri-level apartment just four years after the previous owner, Long Island car insurance executive Penny Hart, renovated it. Hart, who bought the home for a reported $2.5 million and never lived in it, first listed it at $7.7 million in 2012.
