We stayed in Debbie and Steve studio for four nights. It was perfect for us. There is a Muni stop just in front of it that takes you to the city centre in 15 minutes.
There are lots of restaurants in a walking distance.
Also Dolores Park is close, where you have a wonderful view of the city.
During our stay, Steve checked on us by e mail and gaves us a lot of information about San Francisco.
We would definitively stay there again!
