This property is extremely impressive with its expansive floorplan. A corner unit that offers a seamless flow of natural light from oversize windows with eastern and southern exposure. The two direct street access entry ways from Park Avenue and 86th Street are ideal for a high profile clientele that will appreciate privacy and solitude.

This elegant Georgian-style building with some hints of Art Deco was, for many years, the home to publisher Conde Nast, who hosted legendary parties in its custom-designed penthouse high above the Upper East Side. Another unique detail: The 1925 building's three-story limestone base is topped by a tortoise-and-hare frieze that has been adopted by the American Association for the Advancement and Appreciation of Animals in Art & Architecture.

The 14-floor premier co-op is near the Metropolitan Museum of Art, designer boutiques, great restaurants, and art galleries on Madison Avenue. Amenities include: a Fitness Center, private storage with availability, washer/dryers allowed with board approval. 50% financing is required.
