This 6,500 square foot three story condo is hidden behind the classical facade of a 25-foot limestone mansion built at the turn of the 19th century. Located in Upper East Side, a neighborhood of Manhattan, between Central Park and the East River, the four bedroom four and a half bath triplex has received a recent modern renovation by architect Richard Perry with custom-designed finishes by designer Jonathan Adler. This one-of-a-kind apartment was on the market, offered at a mere $20 million.
