Best thing to do on a late Manhattan afternoon is watch the sun set in a different glorious way daily over the Hudson River. You'll experience this spectacle from almost every window of a brilliantly sunny, 2 bedroom, prewar doorman condo at the most tranquil location on the Upper Westside, the reveries of Riverside Park just cross the street. The apartment is in mint condition with 3 luminous exposures and central air conditioning throughout. The foyer is almost 12-foot square. It opens into a 26-foot living room/dining room headed by an enchanting bow front seating area. A pristine, well-designed chef's kitchen is fitted with elegant custom cabinetry, top appliances and an acre of counter space. In a separate wing resides a 17-foot primary bedroom and its luxe en-suite bath featuring a soaking tub and a large separate shower. Both rooms are illuminated by awesome river views. A spectacular 15-foot second bedroom overlooks a wide swath of Riverside Park, the Hudson flowing majestically beyond it. Every evening the sky performs a Tiepolesque light show. There is a consummate live-in super, bike-room and laundry. Pets are welcome. Before "the most inventive and distinctive" firm of Boak and Paris designed the prewar apartment house that now stands at 22 Riverside Drive, Charles P. H. Gilbert, renowned for his lavish townhouses and mansions, created such a one at this sublime Riverside address. It was built for George H. Macy, the major importer of tea into the United States at the century's turn. Mr. Macy could have lived anywhere he wished in Manhattan. Please note that the furnished rooms and kitchen are virtually staged.
