173-175 Riverside Drive is perfectly located across from Riverside Park in one of the Upper West Side's most desirable coops. This mint condition 4BR, 3.5 Bath home has been recently renovated, offering a three zone Nest controlled CAC, new chef's kitchen with Wolf and SubZero appliances, and a separate butler's pantry with wine cooler, laundry and additional storage. The Dining Room has been thoughtfully opened to the Living Room, creating a grand, loft-like experience with brilliant south light. The fourth bedroom, located on the first floor of this duplex, currently serves as a media/den/guest room with an ensuite powder. A dramatically sweeping staircase transports you upstairs to three additional bedrooms, all with ensuite baths. The primary bedroom suite is very generously proportioned and completely private, graced with a dressing room lined with closets and an oversized primary bathroom. Designed by James E. R. Carpenter, 173-175 Riverside Drive is a landmarked, well-established and impeccably maintained co-op with full service staff. The building has entrances on 89 & 90th Streets. Amenities include a fitness center, private storage units (at additional fee), two laundry rooms, a bike room, playroom, and game room. Plush with amenities, pet friendly, and perfectly located across from Riverside Park, this cooperative is the essence of Upper West Side living. 50% financing is permitted and there is a 2% Flip Tax paid by the buyer.
