Description

You?ll understand what I mean after you?ve seen all the done or overdone apartments and found that none are to your taste. 4R offers large rooms, extraordinary light and the best location ?

There is an eat-in kitchen, a washer / dryer in the apartment, high ceilings, ample closets, very low monthly maintenance, oodles of storage in the basement, stroller parking and a shared roof deck with city skyline views. In the heart of Park Slope on a picturesque tree lined street, currently zoned for P.S. 321, with excellent dining and shopping on 5th & 7th Avenues, nearby are the Park Slope Food Co-op and Whole Foods.
