Ask HN: I'm moving to South Bay from Houston (at 18), any tips?

Like on finding housing/roommates, things to see, things to look out for, etc?

I'm moving cross country at 18 to work at a startup, so it's a large change for me and I don't really know what to expect.

I've visited SF a few times and I'm familiar with how the munis and caltrain work, so that's good, but I've never had to look for housing here!

I've looked at sublet housing on Craigslist but nothing really caught my eye. I've also checked airbnb but nothing besides like one week stays :\. I'm looking for short term lease (3 months) as that's the "trial period" where I'll be working, just so I know i'm not stuck with a lease if things don't work out. I'm targeting around Santa Clara since that's where the office will be.

Any help guys?
