I don't know what the rest of the world thinks about the meaning of being a guest in somebody else's house but if ever there is a model of being a host, then Billy and John's one is how it should be intended.
They have been just perfect, as their beautiful house is, making me feel at home since day one.
A lovely mood and a smile every morning, coming with the warm smell of a huge delicious breakfast that changes every day; an amazing private bedroom filled with works of art (as the rest of the house) as well as all sorts of amenities you can possibly need while traveling (cable tv, wifi, even a printer); completed by the most comfortable bed ever.
Best position in San Francisco: two steps away (literally) from 3 buses that take you to either warf/ferry building, to Golden Gate Bridge (Sonoma, Marin County) or to the City Hall area and Market Street.
That was my first try with airbnb and have to say that everything at their place was even better than described: John and Billy are such nice people I can hardly think of being so lucky again in the future. They will be widely missed, and will definitely pop up again in San Francisco, now that I know where to stay.
