Description

Up in the lofty sky of Park Slope sits this classic 2 bedroom co-op at 904 Union Street.

The gracious layout of the open kitchen leading into the living room creates a feeling of space and warmth. The kitchen features enough space for a large table as well as a spacious kitchen pantry and stainless steel appliances. Off of the kitchen is a laundry room with a full sized washer and dryer and plenty of extra storage space.

Separating the kitchen from the living room is an original waist-high detailed wall with an arching column. A beautiful brick mantle frames your wood burning fireplace. Perfect to warm up with a book and a cup of tea on those cold winter nights. Light streams in from two large windows set over the living room.

French doors lead into the second bedroom. Currently set up with a twin bed and dresser. North facing windows let in light. The larger bedroom is also off of the living room and accommodates all of the bedroom furniture you could want. The bathroom is off of this bedroom and features clean white tiles with a waist high blue trim, as well a bathtub with a removable shower head.

Located less than 1/2 block from Prospect Park, the Saturday farmers markets, the Brooklyn Public Library and very close to the 2, 3, B and Q trains, the location of this apartment is fabulous. The unit comes with private storage in the basement and stroller parking in the lobby. Zoned for PS 321
