Description
Remarkable four bedroom, five bathroom prewar apartment on the 16th floor at 9 Prospect Park West, one of the most revered and sought-after full-service coops in Park Slope.

All rooms have nine-foot ceilings. Situated west, north and east, there are 19 windows in total and the major rooms all face the Manhattan and Brooklyn skylines -- so you can enjoy both sunrises and sunsets -- and the master bedroom windows afford views over Prospect Park as well.
