This enormous, high and bright, 3/4-bedroom duplex at a beautiful 155 East 72nd Street (a Park Avenue building off Park Avenue) can now be yours for under $5 million! 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 huge South facing 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. This is now one of the best buys on the Upper East Side "Gold Coast."
