Description

Apartment 7/8D is a stunning duplex home in a full-service Art Deco cooperative in historical Carnegie Hill, less than a block away from Central Park. This gracious three-bedroom, two-and-a-half-bath residence is thoughtfully set across two levels and features an elegant layout with excellent separation between entertaining and private spaces. The main level opens to a welcoming entry foyer with three closets leading to a spacious corner living room and solarium with window seats, as well as a separate sophisticated dining room. Oversized windows bring in northern light and frame lush green trees outside, creating a distinctive sense of privacy. The renovated windowed kitchen is equipped with a Sub-Zero refrigerator, Wolf stove, Bosch dishwasher, Miele built-in coffee station, generous storage, and a washer and dryer. A powder room completes this floor. Upstairs, the bedroom level offers a quiet retreat. The corner primary bedroom is large enough to accommodate a king-sized bed, plus more and includes a walk-in closet with substantial built-in storage. The en-suite spa-like bath features a deep soaking tub and separate shower. Two additional north-facing bedrooms share a hall bath, and a flexible play area sits just outside these bedrooms. All three bedrooms are wrapped in a canopy of trees, its like sleeping in a treehouse. Throughout the home are excellent hardwood floors, abundant closets and through-wall air conditioning for year-round comfort. 15 East 91st Street is ideally located next to Museum Mile, world class cafes and restaurants. Just down the street you will find The Cooper Hewitt Museum with public access to its garden and quick entry to Central Park and the Reservoir via The Engineers Gate. Built in 1948 by the architecture firm of Schultze & Associates in collaboration with the Columbia University School of Architecture, it is an elegant sought after co-op. White glove services include a full-time doorman, live-in resident manager, fitness room, laundry room, bicycle storage and resident storage for every apartment. Pets are welcome. 50% financing allowed and 2.5% flip tax paid by purchaser.
