Cedar Hill Condos Cedar Grove, NJ is a beautiful complex located at the corner of Lindsley Road and Route 23. A great commute for the NYC Commuter since you are only about 1 mile from the intersection of Route 80, 23 & 46. These units are all 2 bedroom and 2 bath units, all are on one level so if you are looking for no stairs in your unit, this may be the place.
