Do you have extra space in your garage or attic?

Hi I am an graduate student at Stanford looking to rent some work space. I am looking for anything with four walls, a roof, and electricity. I'd mostly be working on some art/theater/video projects in the space 3-4 days a week for 3-4 hours during those days. Please let me know if you have an empty basement, storage space, garage, barn, attic, loft etc!!

I can pay up to $350 per month.
Thanks!
Jessie
