daly city. Its less than two miles from sfsu and nhas good transit to other parts of the city.
If you you have to live is sf then sunset or ingleside, I’d think.
And do lots of research, don’t get ripped off. Be patient (if you’re in a position that that’s possible), don’t grab the first place that’ll have you. (I did that. I ended up with a roommate who would masturbate in the living room and not stop as he waved hello when I walked by)
Cheap doesn’t always = you should live there (ie the tenderloin)
