Description

Residence 3C at 21 East 90th Street

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 set, 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 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 a 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, storage, laundry room and only two apartments per floor. The Cooperative receives income from its retail spaces which accounts for the low maintenance.

Pied-a-terre and pets are permitted with board approval and there is a 2% flip tax paid by purchaser.
