Overview of 321 West 90th Street

321 West 90th Street is a charming prewar co-op building located on a picturesque tree-lined block just off Riverside Drive, offering residents easy access to Riverside Park. Built in 1929, the building features a range of apartments, including spacious one-bedroom and two-bedroom layouts, many of which showcase classic prewar details such as high beamed ceilings, hardwood floors, and generous closet space. The apartments are designed to maximize natural light, with multiple exposures and oversized windows that provide stunning views of the surrounding neighborhood.

The building is equipped with modern amenities including a live-in super, elevator access, and a central laundry room. Residents can also take advantage of bike storage and general storage options, subject to availability. The co-op is pet-friendly and allows for pied-à-terre arrangements, making it an attractive option for both full-time residents and those seeking a secondary home in Manhattan.

Many apartments have been recently renovated, featuring updated kitchens with stainless steel appliances, granite countertops, and stylish bathrooms. Notable units include duplex layouts with expansive entertaining spaces and well-appointed bedrooms. The building's reasonable monthly maintenance fees and strong financial standing further enhance its appeal, making it a desirable choice for those looking to settle in the vibrant Upper West Side community.

While the building has seen various renovations, it retains its historical charm, making it a unique blend of classic and contemporary living. Residents enjoy a tranquil environment while being just steps away from the cultural and recreational offerings of the Upper West Side, including dining, shopping, and public transportation options.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
