Berkeley is a nice (and affordable, relatively) place to live for a summer. Living in the city is either expensive, or slightly sketchy, depending on where you live. South of the city is also an option if you can find a place (ie Burlingame, South SF). There's a lot more stuff to do in Berkeley though.
