Description

Sun-drenched prewar one bedroom perfection! Brand new to market is this rarely available high-floor with open exposures on three sides, on a coveted tree-lined Upper West Side block. #9A boasts a gracious prewar layout with proper entry gallery, eat-in kitchen, and large-scaled rooms. Enter into the home to be greeted immediately by high ceilings and an airy feel. The living/dining room, appointed with refinished parquet floors and beamed ceilings, enjoys northern exposure and plenty of sky. The renovated and windowed eat-in kitchen, which has GE Profile appliances, including dishwasher, is fit for a chef. The master bedroom, with corner exposures south and east, is sun-flooded and gracious. It has an office or vanity nook and two large, built-out closets. The windowed bath has been upgraded but kept in original detail. Additional storage is included in the basement of the building. A turnkey one bedroom with this much light is a rare find and one you do not want to miss! 321 West 90th Street is a classic, landmarked prewar cooperative built in 1929 and converted in 1985. The building has a live-in super, elevator, bicycle room, central laundry, and storage facilities. It is friendly to pets, 80% financing, pied-a-terres, and sublets with board approval. Located just steps from Riverside Park, the building is just moments from prime park space, but also the best that the Upper West Side has to offer, including restaurants, gyms, playgrounds, schools, and culture. Transportation is simple, with easy access to the 1/2/3/B/C trains and a close drive to the West Side Highway.
