I assume your daughter will be studying at Widener which is right off of a I-95 exit. The campus is 100 feet from highway -95 so there are no safety precautions as far as crime and I-95 is so backed up with traffic between Philadephia and Chester that its almost impossible to exceed 40 mph so no safety issues there as well.
Chester is no paradise but Widener's campus is actually very nice, secure and small. The security on that campus is overwhelming and noticeable, its probably one of the safest campuses in this entire region.The hoodrats from Chester dont come near Widener, they know better.
If money is no restriction Rittenhouse Square/Soceity Hill is the place to be imo. University City would also be an excellent choice as University of Pennsylvania recruits alot of international students.Tons of college aged people in University City and it might be the most culturally diverse part of the Philadelphia area.
Good luck. Here is a photo of Philadelphia looking at downtown. Rittenhouse is as you approach the skyscrapers. University City would be just to the left out of of the frame.
One last thing if you find the city not to your liking you can look into Swarthmore and Media which are very nice towns(small) near Widener.(10 minutes away)
