Doug was a really good and helpful host. I arrived a bit later than I planned but he was there to greet me with a big smile. The room is nice and spacious, just as on pictures. Even though there is only one shower room in the house I felt like I was the only one using it throughout my stay. Location is just perfect for exploring SF, i walked to Castro in about 25 mins. There are buses that will take you to Fishermans Warf, Union square, Mission, etc.
Be ware that there are 2 cats in the house, they are very human friendly, but if you are not a cat person, then it might be a problem.
I would definitely recommend Doug's place as a base for exploring SF.
