We had a great stay at Tim's house in San Carlos. The room was very private, clean, and comfortable. The bathroom, which is shared with the other room he rents out, was super nice too. We didn't get to see Tim much (our fault because we were so busy) but when we did talk, he was very friendly, laid-back, and helpful. I would definitely recommend staying here! It's a perfect central location in the Bay Area, with a great host and comfortable room. Tons of street parking too! It was a great first experience with Airbnb.
