Property Description for 21 East 90th Street, 3-C

Charming Prewar Classic Five Room with Low Maintenance

Entering through the gracious foyer from a semi-private elevator landing, one is immediately struck by the size and scale of each room, the high ceilings, the beautiful hardwood floors and the sunny east-facing wall of windows. The living room features custom built-in bookcases, storage and a stately decorative fireplace mantle. The elegant dining room separates the living room and the kitchen and has a large hidden walk-in closet. The heart of the home-the windowed eat-in kitchen-features Bertazzoni and Bosch appliances, a charming tripartite window, room for a comfortable kitchen table, along with a washer/dryer and separate service entrance.

On the opposite side of the apartment, there is an elegant hallway separating the two king-sized bedrooms from the living area. The sunny primary bedroom faces east and has built-in bookshelves, an en-suite windowed bathroom and a large custom walk-in closet. The 2nd bedroom faces west and has a windowed en-suite bathroom and large closet of its own. There is built-in thru-wall AC in every room, and the apartment transfers with storage.

21 East 90th Street is an esteemed Carnegie Hill white-glove full-service cooperative built in 1927 by notable architect George F. Pelham. The building features a 24-hour doorman, on-site resident manager, recently renovated lobby, an exercise room, courtyard, storage, laundry room and only two apartments per landing. Pied-a-terre and pets are permitted with board approval and there is a 2% flip tax paid by purchaser.

Carnegie Hill | Manhattan

Quick Profile

Carnegie Hill is a small neighborhood at the northern tip of the Upper East Side that borders Central Park. It is steeped in history, great wealth, architecture and culture. It is known for its world-class museums and its rows of historic mansions. Nothing much changes here as the entire area is landmarked, preventing the proliferation of high-rise developments. Thus the buildings stay a human scale, the sky is aplenty and the neighborhood kind of feels like a small town to its long time residents.

The name Carnegie Hill is derived from the industrial magnate Andrew Carnegie, when Carnegie decided to build himself a mansion at 91st Street and Fifth Avenue….

Carnegie Hill is a family neighborhood with old fashioned upper crust money. The mid-rise co-ops that line the avenues are among the most prestigious addresses in the city. The avenues are lined with small restaurants, boutique shops

The residential towers that have proliferated on the eastside of Third Avenue in the East 90s simply do not exist between Lexington and Fifth.
