Ask HN: Can anyone help me here?

I got accepted to the MakeGamesWithUs summer internship in San Fran but I don't have a place to stay and I don't know anyone out there. I'm from the midwest. Being 17 kind of makes my situation a little tougher. I really want to go to the internship but finding a place to stay is my problem. I plan to be there for 4-6 weeks which makes my problem even bigger because I don't know if anyone will allow me to stay with them for that long.

If anyone can help me, please let me know. I'm sort of desperate. I need to know by June 5th.
