The Piazza is in the heart of everything up-and-coming in Northern Liberties. Public transportation is a five minute walk, and on the subway it's 11 minutes to Center City. Enjoy a view of the city from bed with a canopy over your head.
The Piazza is an event venue -- there's always something going on in this area. You'll be near some of the best bars and restaurants in the Philadelphia area. You will share the apartment with three ladies (although not all three will be present during Pope visit). It is a tri-level that has access to a communal rooftop deck that has a great view of the skyline.
The bedroom will be all yours, and you will share a bathroom with just one other person (but she works a lot and works long hour). The kitchen and living room are common areas but everyone is extremely nice. You'll be able to take advantage of the grocery store (not even a five min walk) and store some food in the refrigerator. The apartment comes with a gym, so I can give you my card which allows for full access.
