I have no reservation in using airbnb again or recommending them to others. It was easy to use their website to make a selection and everything was as they said, no surprises. Booking a house worked well for our group and ended up a lot cheaper than several Hotel rooms. Having our own kitchen meant we saved even more on not having to eat out for every meal. The house was well equiped, with a supermarket across the road as was the bus stop to take you to the BART train station approx a mile away (steep hill, San Francisco!) A 15 minute train ride and you are in the middle of the city.
Our Host Bruce was very helpful and friendly, he even greeted us with some pastries from his Bakery. He was easily reachable and gave us useful information that helped us get around. We covered a lot of ground and it was great to get a bit of local knowledge. Overall a pleasant experience with no real negatives, I and everyone else in our group would stay there again.
