David and Kevin are more than simply providing a room. They do it professionally. Their house is awesome, very clean and cute. What made me impressed is how they care about every little detail: there are even San Francisco city guides in the room. Even if you are the type of person who does not like dogs, you should not worry about Buddy, the dog: he is very lovely, and virtually invisible - you won't even notice he is around. And the most important: they are really cool people. I felt at home almost instantly, Kevin helped me with my laundry and David cared enough to take me for a tour ride around the area, including Stanford university. Last but not least, the house is very close to the freeway and there are lots of facilities nearby. I will never be staying in a hotel on my next strip to Northern California again.
