Johanna and Bob are amazing hosts. My wife and I stayed at a room in the first floor for 2 weeks, while working for a startup as an intern. Their house is really clean and quiet. Since Caltrain station and downtown San Carlos is within walking distance, it was convenient to go out for dinner and sightseeing for San Francisco. We could have used kitchen, and I enjoyed having conversation with Johanna, Bob and the other guests. If I visit the area again, I will definitely stay their place. Thank you, Johanna and Bob!
