I have lived in Rose Hill II for over a year now and have had absolutely no problems. The people who live around me are all very quite and I hardly ever see them.
When we do have a problem with something that needs maintenance, we inform them upon paying rent, and they are there within a couple hours.
Parking is usually okay, other than during the holidays when random cars are in your usual spot..
The only real negative I have here is that your not allowed to own a dog of any size in the apartments, just cats.
Aside from those few things, Rose Hill is great compared to everything I've seen so far in West Chester (taking price & size into consideration) and the places I have lived before.
