Description

ALL OPEN HOUSES BY APPOINTMENT ONLY - VIEW VIDEO FORE MORE INFORMATION From the moment you enter the elegant foyer of this grand prewar home, you will be awestruck by the scale of the living and dining rooms and the views that are framed by the huge picture windows. The spectacular primary bedroom has jaw-dropping west River and south city and park views. The en-suite windowed bathroom was recently renovated and now has a glass-enclosed stall shower. The two other spacious bedrooms also have sweeping river views, original en-suite bathrooms, and enormous closets and storage. The sleek windowed kitchen was reconfigured to offer a very spacious eating area with a banquette, an abundance of counter space and cabinets, and top-of-the-line appliances including a vented six-burner stove. Additional features of this truly special home are a home office or fourth bedroom with an en-suite fourth full bathroom, a washer/dryer, through-wall A/C, retro radiators, soaring ceilings, and parquet floors. 90 Riverside Drive is a majestic prewar co-op that is pied-a-terre and pet-friendly. There is a gym, basketball hoop, playroom, roof deck, deeded storage bins, and two bike rooms. The phenomenal staff offers white-glove service with doormen and, of course, a live-in resident manager.
