This impossibly spacious three-bedroom duplex maisonette in a gracious Upper East Side pre-war co-op at 520 East 86th Street is really a “best of both worlds” situation. For the price of $4,755 million, you get the privacy and space of townhouse living on two floors, three bedrooms and your own private entrance with its own address. You also get the convenience of a full-time doorman and a chance to live in a covetable Manhattan co-op.
