When I was at Hahnemann, it seemed pretty nice. The facility itself is pretty new, and they were really touting their technology. The students were also quite friendly. And the curriculum is pretty modern (with PBL and that whole bit).
The downsides: cost (it is a private school), and while the area immediately surrounding the school isn't bad, once you get a few blocks away, you're in an area that I woudn't really want to be out in after dark. Also, the hospital is ~20-30 min away in downtown Philly, so that could be a hassle, I suppose.
Also, I notice you didn't mention Temple, which is also in Philly. I didn't apply there, so I can't say anything about it, but just thought I'd throw it out there.
