Property Description
Why rent when you can begin your homeownership journey right here? Welcome to this truly distinctive duplex residence, offering an uncommon two-level layout in an intimate prewar cooperative on the Upper East Side. Combining the convenience of multi-level living with the amenities of an elevator building, this move-in ready home enjoys a coveted first-floor position, allowing for effortless access without the need to ride an elevator, while still maintaining the option to do so. Inside, warm parquet floors run throughout the home, while the updated kitchen allows for both everyday living and entertaining. Rich cherry cabinetry is paired with polished black granite countertops, a breakfast bar for casual dining, an undermount stainless steel sink, and a full suite of newly upgraded appliances, including a dishwasher and microwave. The apartment is vacant and ready for its next owner to move right in. The residence features a spacious bedroom with custom built-in shelving and a ceiling fan, while the adjacent bathroom is clad in Italian marble and a new vanity provides additional storage. Generous closets with built-in organization, through-wall air conditioning, and elevator access from both levels add to the home's exceptional functionality. Built in 1910, this intimate, award-winning cooperative consists of just 34 residences and was created through the thoughtful merging of two historic brownstones. Residents enjoy a live-in superintendent, elevator, laundry room with brand new machines, and a beautifully landscaped private garden. Located in the heart of the Upper East Side, you'll be moments from Central Park, Carl Schurz Park, John Jay Park, renowned museums, neighborhood cafés, restaurants, specialty markets, and convenient transportation. The building permits pets up to 25 pounds. Subletting is permitted with board approval after two years of owner occupancy, with a minimum one-year lease term and a maximum of three out of every five years. Co-purchasing, pieds-à-terre, parental purchasing, gifting, and guarantors are reviewed by the board on a case-by-case basis. There is an ongoing assessment of $72.60/month through May 2028 for Local Law 11 work.
