Hi there , I live in the bay area so I'm not very sure about the cheapest hotel , I have stayed in some in the past non cheap . The Utah Inn was a great place cheap price. Hopefully you have a great time and enjoy your stay !
I've stayed at the Jack London Inn at Oakland. Take the Bart Train to San Francisco and get off at the Embarcadero station. I also have family living at Oakland as well.
Better to stay in Oakland. Cheaper and just across bridge
Frances, here are few places: Courtyard S.F. 299 2nd St. $74 and Oakwood @ 399 Fremont $80
Away from the city area.
