Is a $700 budget realistic for a shared apt at a safe neighbourhood < 20 mins from campus

*excluding utilities. For context, I am an incoming SEAS graduate student. I want to spend most of my time on campus or exploring Philly, so I wouldn't need a super big space. Also, as a woman, I am very concerned about my safety, especially when returning from campus after sunset. I would appreciate suggestions regarding what apartments I should consider. Thanks!
