Billy and John are great host, they are very warmhearted and Billy even picked me up at the station when I arrived late in the first night. Their house is a beautiful little gallery with a lot of lovely plants taken care by John, and Billy is sooo knowledgeable about the city, they provided everything more than I need when I was stay. The neighborhood is nice to walk around and just one block away the MUNI station, good cafe and tea shop are within walkable distance.
