Temporary Housing & Transportation (LLNL intern)

I've been offered an internship at LLNL for summer 2025, however, I live across the country so I was wondering if anyone could give some advice related to housing and transportation in the area for interns.

Is it feasible to use a bike as your primary mode of transportation? Any areas to avoid, or areas that would be good to live? (I've seen negative posts about a few apartment complexes already.) Is there a group or some resource I should be using to find housing?

I'd be pretty excited about the position, but the high cost of living and >2000 mile move are daunting.
