short-term housing needed (week-long) - couch or spare bedroom

Hi,

I am looking for a short-term housing or sublet for the following periods of time:

October 18-26, 2010
November 12-19, 2010
January 9-13, 2011

I am trying to find anything from a decent couch to a spare bedroom (separate or shared room, furnished or unfurnished, it doesn't matter) that I can rent for these short periods of time. On-campus or very near campus preferred, as I won't have a car (EV would be perfect, but other biking distance locations are OK).

I finished my doctorate at Stanford last June and now I will be coming back for a post-doctorate.
If you have a space available for any one of the dates above, please get in touch. Depending on the space you have, I can pay you something between $150 to $250 for a 1-week stay.

I'm pretty flexible to discuss alternative arrangements. I'm male, mid-30s, very quiet and clean, and will be spending all days at work in my department (pretty much just coming back to sleep at night -- I can assure you my stay would be 'low-impact' in your house).

Thanks.
