Housing needed May 15th onwards (for 3 months)

Hi,

I am writing on behalf of my friend coming from Columbia University (NY) to the Bay Area for a summer internship. He needs housing for 3 months starting May 15th. Since his workplace is in Sunnyvale, any where from Stanford/Menlo Park till Sunnyvale suits him fine. He is looking for a reasonably priced apartment (shared housing is fine as well). Please reply if you have a good suggestion.

Thanks.
