I am from OC and went to SFSU for my undergrad. Yes, it is expensive to live up there but you can easily find roommates and shop around. The area around the school (Sunset, Ingleside) is pretty safe for the most part and filled with students. I lived in the Sunset and paid 1200 a month for my own bedroom in a large house with 3 other people, but people I know shared rooms for 600. Transportation wise, the SF muni is included in your student costs so you ride for free. I would definitely not use a car as your main form or transportation to school if you are concerned about money, because parking is outrageously expensive and adds up fast. Program wise, I have some complaints, mainly about lack of organization, but it could be better in the graduate program. I also spent time as a clinic aide in the on-site clinic. Definitely not high end stuff (the cameras for the supervisors barely worked) but they have all the materials you could need and knowledgeable supervisors and professors. Overall I loved my experience there. SF is a fun place to live, especially if you're coming from a place like OC.
