I love a Residence Inn!
This Residence Inn is in a great location for all that you want to see in Philadelphia. I had a King one bedroom suite. It was spacious and inexpensive for being in a city in a good location, 189.00 a night. Free breakfast which was good and plentiful, my only complaint here was stale Fruit loops for my daughter. The staff were all courteous and Jorg was especially helpful with our car and information. The fitness room had a good mix of equipment. 
I do love staying at a Residence Inn anywhere I can. I have always been pleased. I think they are great places to stay, especially if you are bringing the family.
