Yvonne's and Marc's house is much better than I expected. I booked their master room with private bath for 1 month and, by the end of my booking, I was looking for an extension for at least more 2 months! (ultimately I moved to another house because of my work). They are fabulous hosts and great people. They helped me with everything I needed since the moment I arrived: I was allowed to use their guest bike every day for free!; Marc was always ready to give all sorts of tips about places to eat and buy groceries, better routes for cycling in the city, how to wash my clothes properly, etc; Both Marc and Yvonne helped me with my pronunciation and other mistakes foreigners usually commit when speaking English. To sum up, I felt like home in their place. If you are in doubt about where to stay in Cupertino/Santa Clara/Sunnyvale or if you think that the price might be a little bit more expensive than your budget (everyplace in the bay area is expensive), don't hesitate: book this room. You won't regret.
