My studio is in a beautiful neighborhood called Graduate Hospital, which is within walking distance for all of the events going on the weekend of the Papal visit. The area has lots of great restaurants and bars right out on South Street as well.
This studio is deceptively roomie and has a cute kind of charm to it. The large windows make it very bright and look out on to a great view of the Philadelphia skyline. It's very comfortable and a place that I love coming home to every day.
You will have full use of the apartment.
I will likely be staying with my mother the weekend of the Papal visit. She lives out in the suburbs about 15-20 minutes away if you needed me for anything.
The couch does pull out to form a full-sized bed. I listed the apartment as accommodating 3 guests, but you could comfortably sleep 4, I think.
There are other tenants in the building (one next door and one on the floor beneath you). Just do not be too loud, especially after 10. There is also no smoking in the apartment.
