If you're familiar with the area, try to stay away as far from Temple as possible. Temple is in a ghetto area. It's not very safe. The hotels in Center City area are good but they are a bit expensive. The prices range from $100-$200. You can take a bus or subway to Temple
Try the holiday inn express, only about a block from the subway and lets off right by the dental school, about 10-15 minute ride. Plus, if you tell the hotel that you are staying for an interview, you get a discount (can't remember how much)
