Staff was friendly. Room was clean but did not have a window that opens and smelled like air freshener. Some wallpaper and the bathroom ceiling showed the building's age. They charge a $20/day fee and give a $10 credit that can only be spent at the in-house Arts Café (not a true café). No room service, as far as I could tell. It's nice but not exactly affordable for what it is. Centrally located, close to SEPTA stops.
