Need furnished home to rent while at Stanford on sabbatical

Relatives of a Menlo Park friend are professors at the Univ. of Wisconsin who will be arriving in mid August to be at Stanford on sabbatical for the coming school year. They have been looking for a suitable furnished house, townhouse, apartment, etc., but have so far been unsuccessful. They have a son in high school (very well-behaved). If you happen to know anyone who would like to rent out their house, or have any good ideas, please let me know.
Thanks,
Virginia
