Description
Welcome to Hardenbrook House, the Upper East Side's premier full-service condo building and location of the newest, largest alcove studio to hit the market. Measuring at 550 square feet, unit 3K is the perfect home for someone who appreciates the efficient manner in which this line is laid out. Upon entering, you will find a wall across from the kitchen lined with 3 large closets, one of which is a pantry. As you enter the airy open space is a nook perfect for a high-top table set which is already appointed with a modern, tasteful pendant chandelier. Continuing toward the south-facing wall of windows is the living/sleeping area that is large enough to configure in multiple ways. Across from the sleeping area is a roomy bathroom that is complete with a walk-in changing area that includes another large, double-wide closet with sliding, mirrored door. This building is centrally located just a short walk to various subway lines, including the 72nd Street N/Q, as well as the 68th Street 4/6 train and the Lexington Ave./63rd Street F/Q lines. Additionally this building is around the corner from the New York Weill Cornell Medical Center and the Hospital for Special Surgery, not to mention in close proximity to all the restaurants, shopping and sites that the Upper East Side has to offer. Hardenbrook House Condominium consists of 158 units and features a full-time doorman, laundry room, parking garage, and a beautifully appointed courtyard. Ongoing assessment of $77.99 to be allocated to elevator modernization as well as hallway/lobby improvements. Photos partially virtually staged. Gifting, pied-a-terres and co-purchasing are all welcome and pets are allowed.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
