Description

Prepared to be enthralled and to fall in love. Not a ground floor apartment, this stellar example of prewar charm has been magnificently restored. The experience begins as you enter 645's magnificent lobby, designed by architect Gaetan Ajello with grand embellishments including soaring 20-foot ceilings, feature-wall of original stained glass, marble and travertine floors and iron balustrades. Upon entering the home your eyes are drawn up by 13-foot ceilings, setting the tone for the entire apartment. Improvements are evident at every turn and include a multi-zone central air conditioning system. Every room is a statement of elegance and the open flow makes for great entertaining. An airy chef's eat in kitchen features Viking appliances including a gas range, convection microwave and a 44-bottle wine refrigerator, and has incredible storage, quartz counters, textured backsplash and under cabinet lighting and power. The kitchen flows into a former maid's room converted into a state-of-the-art home office and laundry room with Bosch washer and vented dryer. The dining room is a space you will use every day featuring stunning restored oak-paneled walls, a soaring beamed ceiling and custom chandelier. The dining room flows seamlessly into an adjacent living room with 9 foot-framed windows and original, restored parquet flooring. The wall of the living room has been opened, creating flow into an adjacent media room that also functions as a guest bedroom when separated by the custom mahogany sliding wall. Conversion back to a dedicated 2nd bedroom is easily accomplished. The master suite with double fitted closets is an escape unto itself and its en suite bath boasts an original stained glass window which provides privacy and warm, morning light. The second hall bath has been lovingly updated and includes stained glass as well as a shower/soaking tub combination. This apartment feels much more like a town home thanks to the 13-foot ceilings that dominate the space, giving a sense of grandeur that is beyond comparison. Built in 1912, 645 West End Avenue holds a prominent place on the avenue architecturally. It's amenities include a 24-hour concierge, magnificent roof deck overlooking the Hudson River, a 24/7 gym, storage, live-in super and maintenance staff. Life on West End Avenue does not get much better than this building with its location equally convenient to the lushness of Riverside Park and every convenience New Yorkers expect.
