Billy is really a warmhearted host. He and Jon replied to our needs quickly during our stay. The location is really ideal for those who wants to have a city tour in San Francisco. We used uber and lyft a lot when visiting the Golden Gate, Pier and Union Square etc. All the rides didn't cost much. And also the house is very comfortable and well decorated. And plus, it's been nice to talk to Billy. Thanks for all the advices on our trip.
