Hi,
I'm a female grad student in engineering here and I'm going to be working on campus for the first 6 weeks before going to India. I'm looking for any sort of rooming situation from 6/14 to 7/18, but what would be ideal would be for me to room with you in whatever sublet you've already got and split rent (you could save 1/2 of your current rent this way). I'm small, clean, quiet, and respectful, and I'd be in SF a couple nights per week. Let me know how this sounds to you!
