The floorplan of this renovated apartment has been reconfigured to include three full bedrooms and is now six rooms instead of the original seven. The semi-private elevator landing opens into a large and inviting gallery. The entertaining rooms all radiate off the gallery and easily flow one to the other. The side-by-side Living Room, with woodburning fireplace, and Dining Room are connected to each other via wide pocket doors and are perfect for formal or casual entertaining. Both rooms look out onto the East 77th Street townhouses. A private hallway leads to the bedroom wing, featuring a corner master bedroom with a luxurious en-suite bath and plenty of built-in storage and closet space. The second bedroom is currently used as a library. The second and third bedrooms share a spacious and well-appointed hall bath. The comfortable windowed eat-in kitchen is outfitted with top of the line appliances. A powder room and laundry area are each accessed from the kitchen. The apartment is centrally air-conditioned. 850 Park Avenue is an exceptionally well-run, full service cooperative. The building is pet friendly and amenities include storage, bicycle storage, fitness room and a play area. The building allows 30% financing and there is a 2.5% flip tax.
