Elegant and Opulent are the words to describe this extraordinary duplex in the legendary Hotel des Artistes.  Resplendent with original details - most notably, a beamed and painted ceiling restored by Smithsonian conservators, a majestic carved staircase, and a stunning carved stone wood-burning fireplace - this 2BR/2 BA home with separate maid's room is perfect for gracious living and entertaining.  With its graceful layout, the foyer leads to a stunning and expansive 28' living room with a soaring 18'10" ceiling and 14' windows.   The adjoining dining room, so spacious it is used by the current owners for both dining and an office, opens to a small balcony overlooking an historic church dome.   A renovated, windowed kitchen offers custom cabinetry, artistic painted tiles on the walls and countertops, a Sub Zero refrigerator and a separate pantry.   Up the sweeping staircase are two bedrooms, one with an ensuite bath and walk-in closet and the other features a luxurious marble bath with an oversized tub.   Light and sunny, one of the bedrooms has a peek of Central Park as does the living room.   One of the premiere buildings on the Upper West Side, the Hotel des Artistes is a full service cooperative with amenities not often available in prewar buildings.  These include a swimming pool, two workout rooms, a squash court and a serene high-walled roof garden.  Residents are also afforded room service from the Leopard at des Artistes as well as a discount on dining and use of a private dining room.        Built in 1917, the Hotel des Artistes is a majestic 18-story building with a Gothic-style facade featuring charming gargoyles of painters, sculptors and writers.  Designed by the architect George Mort Pollard, the landmarked building has been home to many of the famed and illustrious, including Noel Coward, Isadora Duncan, writer Fannie Hurst, New York City Mayor John V. Lindsay, Alexander Woollcott, Norman Rockwell and Joel Grey. The Hotel des Artistes is the most prominent building on a lovely tree-lined block off Central Park, often referred to as "Artists Row," and listed as the "West 67th Street Artists' Colony Historic District" in the "National Register of Historic Places."
