Michael's flat is quite small but cozy and close to a nice street with sportbars and a few restaurants..We weren't in touch with Michael but with Addy,a friend of him and she was really helpful with everything we needed.
At the time we stayed at the flat there were no wifi nether the TV was working which was a bit of a problem but Michael warned about it before.
If you don't need a big place to stay in sf I suggest going to michael's place
