This stunning duplex aerie is perched atop an elegant 25 foot wide limestone mansion, with elevator. On a quiet tree-lined street off Fifth Avenue steps from Central Park and the Metropolitan Museum of Art, 16 East 80th Street was one of the earliest blocks in the Historic District to have houses built upon it. The versatile layout of this thoughtfully designed duplex boasts a wood-paneled Living/Dining Room with 10'9" ceilings overlooking the historic mansions and treetops of East 80th Street. The grand center 20'10" foot stairway defines the scale of this special home. A south-facing Library/3rd Bedroom with an en-suite marble Bathroom and a custom designed gourmet Chef’s Kitchen complete the upper level. Downstairs 2 Bedrooms, each with a luxurious en-suite marble Bathroom, may be easily converted to a single grand Primary Bedroom suite. This floor features a separate entrance and a 4th full Bathroom. The meticulous renovation includes thermostatically controlled through-wall air-conditioning, hardwood flooring, and superb stonework and custom designed millwork throughout. Installation of a washer/dryer is permitted with board approval. Recent improvements to this well-established and beautifully maintained 8 unit cooperative building include a new elevator, roof and newly decorated Entry and Hallways. A true Manhattan classic, in the heart of the Metropolitan Museum of Art Historic District.
