I had the opportunity to stay with Johanna and Bob for an entire month. It was a really pleasant time. My room was nice and tidy, they have an excellent wi-fi connection (which was very important for me as I was on a business trip), they offered great breakfast with lots of fruits, and – most important – they are really great hosts. If you have business to do in Silicon Valley, their wonderful home in San Carlos is the ideal starting point - right in the middle between San Francisco and Mountain View. During my stay I met a couple of other guests who came here for the second, third or umpteenth time. That speaks for itself. If I have to do business in the Valley again I certainly would like to stay with Johanna and Bob again.
