Now available for the first time in many years, this very large, very high duplex at beautiful 155 East 72nd Street will wow you. Redone in stylish mid-century taste, it enjoys streaming southern light through huge windows on both floors. The 540-square-foot living room with a fireplace, laid out along three windows, flows into the equally spacious dining room which benefits from both southern and western exposures. A cozy den, a full bath, and a large eat in kitchen complete this floor. Upstairs is an elegant library, also with a fireplace, three spacious master bedrooms each with its own bath, and a dressing room/office off the master.
