Location is great, close to BART, caltrain and airport if that is what is important to you. Host is super nice and friendly and will help you with anything. Place is suitable for kids, has a cot, we even got some toys which was really nice.
Flat is meh, could use a trip to IKEA.
I do not have experience with competition in the area, I know price of housing there are insane, but despite that it seems expensive.
