Need couch on/near campus for rent (oct-nov)

Hi,
I'm a female grad student (23) doing an exchange quarter at stanford and need a place near or on campus. I have family that is a longish commute away so i will likely be staying with them a few days a week but I would like to have a place near campus where I can crash, so a living room/couch will do (obviously I will contribute to rent at a negotiated price). I am neat and friendly, and dont't travel heavy (so your living room will not be a mess). I mostly need space for October and November. Let me know if you might have something for me!
Thanks!
