I'm at a university on Walnut Street just south of a Cosi fast food sandwich place and southeast of a Hilton across the street. I would say go west across the river and keep going until you almost get to Drexel University but go south 2 blocks at that intersection and you'll be at Walnut Street. Then head west about 3 blocks and the school is on the southwest corner of that intersection. You will pass two post boxes a CVS pharmacy and a Dunkin' before you get to the university I'm at.
