Bruin,
I'm also in the process of looking for an apartment. As for the student housing, I think the chances of getting a room will be really slim plus you have to share a room with someone. Another factor is that the first year housing is like 1.5 miles away...
I have a sister who lives in SF she is looking for another apartment around the Sunset District. You can check out the housing site on the ucsf website or go to <a href="http://www.craigslist.com" target="_blank">www.craigslist.com</a> for more listings for apartments and rentals in SF. If you can, get a map of the public transportation routes for SF, so that you only have to take 1 bus to school. THere's actually a streetcar Line N that goes along Judah and this will take you straight to UCSF.
Hope this helps!
