Looking for housing from July 15 to October 15

I am a Stanford ICME alumni and I have a colleague (PhD student, male, 30) from University of Munich, Germany, who will be visiting a research lab in Palo Alto (Porter Drive) for a 3 month period starting July 15. He is looking for a furnished room (bonus if own bathroom) in Palo Alto, Menlo Park, Los Altos, or Mountain View, or maybe even Redwood City or somewhere close to a Caltrain station. He is a friendly and outgoing person, neat and organized, and reliable. Please message him (sanjeevkrn@yahoo.com) if you have anything available for him!
