Hm. I guess I should hurry. If you don't mind my asking, how did you search? I also have a friend who's looking for apartments for me, and I've been using phillyapartmentco and craigslist. And the Penn Off Campus website although that's not too great.
The Eastern State Penitentiary is a National Historic Landmark! I believe it actually held Al Capone at one time. I would *not* like to live next to an actual penitentiary =) I believe they put up a great Halloween show, though, which sounds like fun. Senior year of college, my room overlooked a graveyard, I'm used to spooky places =)
