Need place for Summer

I need a place near campus or in SF from 6/14-9/21 (start date flexible, end date very flexible). I am very neat and considerate and do not smoke. I am interning in SF over the summer and I would like to stay close to campus. Furnished preferred. My only requirement is that the place has easy access to Caltrain by bike or bus. Feel free to contact me at jamesnie@stanford.edu if you have any questions. Thanks.
