AKA is the closest, about half a block away. (https://www.stayaka.com/aka-university-city) Other options include The Study (https://www.thestudyatuniversitycity.com/rooms.html) and Sheraton (https://www.marriott.com/hotels/travel/phlus-sheraton-philadelphia-university-city-hotel/).
I wanna say Sheraton University City, but it's not too far from Center City...
I'm not sure. I'm local but it's on the University of Pennsylvania campus so I'm sure they'll be choices.
