Student seeking room for summer internship

Hello! I'm (21m) looking for a place to stay for the duration of my summer internship (May 13 - August 2).
I'll be working in Pleasanton but almost anywhere in alameda county should be fine to stay as I'll be bringing my car (and will need a place to park it).
Would really prefer to be paying $1000/month or less but I am open to all offers.
A bit about me: I'm from North Carolina but was actually born in the bay.
I study aerospace engineering which relates to my work this summer.
I love building things, computers, music, and going out with friends.
