Here is a rare opportunity to acquire the only available home in this sought-after prewar coop in the heart of Carnegie Hill. This classic six-room two-bedroom home has been happily inhabited for twenty-five years by the current owner but it is now time for a new owner to renovate this elegant and quiet home and bring it up to today’s standards of taste and design.

Here is a rare opportunity to acquire the only available home in this sought-after prewar coop in the heart of Carnegie Hill. This classic six-room two-bedroom home has been happily inhabited for twenty-five years by the current owner but it is now time for a new owner to renovate this elegant and quiet home and bring it up to today’s standards of taste and design. The layout is excellent—on one side of the 16+ foot long gallery is a formal dining room entered through French doors and a spacious living room graced with a wood-burning fireplace, high beamed ceilings and other prewar details. On the other side is the bedroom wing with a large master bedroom and en suite bath plus a second similarly-sized bedroom and full hall bath. Through a pantry is a windowed kitchen and staff wing which offers a bedroom or office, a hookup for a washer-dryer and a staff bath that can be restored to a full bath or powder room. This top Carnegie Hill building offers very low maintenance due to its elegant retail stores along the Madison Avenue side and also provides a discreet entrance through the attractive lobby on 90th Street just down the tree-lined block from the entrance to Central Park. There are 24-hour doormen, an attentive live-in super, a free laundry and a bike room plus a private storage bin that transfers with the apartment. The location could not be better—surrounded by major museums, many charming restaurants and shops, top private and public schools and the Park, this is a rare gem. The proximity to bus and subway transportation makes this an ideal place to call home—plus you can bring your pet.
