I'm living in San Francisco while taking time off from school and found myself managing a property in the mission district. Its a beautiful home in a cool neighborhood with a kitchen you can use and a small back yard. I live here with 3 other tenants/friends. Occasionally one of us leaves for a few weeks in which case it would be a available for you to stay. On top of the Airbnb terms of conditions my main thing is that you must realize that you are paying for use of the room, but this is not a hotel and neither me nor my roomates are here to serve you. As long as everybody is respectful and contributes, there will be no problem.
