Across from Central Park at 67th and Fifth Avenue, discover this exceptionally serene and private Duplex/Maisonette. The 44 foot by 14 foot private terrace is shaded by a wisteria covered pergola, has automatic irrigation, and is the backdrop for an airy living room and formal dining room, both illuminated by a 40-foot wide floor-to-ceiling glass wall. A windowed kitchen is just off the dining room. Almost nine-foot ceilings, built-in custom wet bar, guest powder-room, and large walk-in closet complete the ground floor. Ascend via stairway or elevator to the second floor, to discover a huge master bedroom with two en-suite baths and three large walk-in closets. There is an additional bedroom with bath, and a large library/media/bedroom. The apartment has central air conditioning and unusual closet space. 857 Fifth Avenue offers its owners exceptional white glove service, and is a short distance to some of the most favored restaurants and shopping on the Upper East Side. There is a 2% flip tax paid by the seller.
