Room for Rent in Piedmont Area for Weekdays Only

My son is currently in college and his room with private bath sits empty most of the time (he does still come home for visits on occasion). There is a queen bed, desk, and dresser in the room; however, his items occupy the desk drawers as well as some of the dresser drawers. I have emptied out most of the dresser drawers and made room in the closet and bathroom for the previous commuter guest that occupied the room, which seemed to work well. The last guest, who lived in Hollister and commuted to Oakland, just began working full-time from home; hence, leaving the room available for another commuter looking for a room in the Piedmont area 1-3 nights per week @ $60 per night.
