Description
Hidden Gem. Private Rooftop. Just Off Central Park. A one-of-a-kind gut-renovated duplex nestled in a 19th Century Georgian mansion, this special 2-bedroom, 1-bathroom co-op is a unique blend of light, modern luxury, and classic New York City charm. The spacious rooftop sanctuary possesses lovely neighborhood views and is ideal for sun lounging, cloud gazing, entertaining, al fresco dining, and urban gardening. On the lower level of the home, the entryway flows past a lovely set of stairs and into an open-concept living, dining, and kitchen area saturated with northern light. Beautiful hardwood floors run throughout the space, and custom built-ins offer convenient storage solutions. The kitchen is equipped with custom cabinets and shelves, sleek stone countertops, a glass tile backsplash, an eat-in peninsula, and a suite of high-end stainless steel appliances. The primary bedroom is large enough for a king-size bed, while the second bedroom can easily accommodate a queen. Both bedrooms have easy access to a luxurious bathroom with custom tile work, contemporary fixtures and finishes, a walk-in shower, and a separate soaking tub. The upper level of the home features a cozy sleeping loft, a wall of storage closets, and access to an outdoor escape in the heart of the Upper East Side. 18-20 East 84th Street is a landmarked mansion-turned-co-op located less a block from Central Park. The building has a part-time doorman and an elevator, and it is moments from The Metropolitan Museum of Art and The Guggenheim. Plenty of dining and shopping options are available on Madison and Lexington Avenues. Nearby subway lines include the 4/5/6. Pets welcome. Subletting is 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.
