Coleen and George are fantastic hosts, very helpful and approachable, but never intrusive. We had a great time, the house is located in a nice leafy neighbourhood and it's very spacious, clean and functional as well as beautiful. Plenty of trails nearby (we were there for a trail race at Lake Chabot) and easy access to Oakland, Berkeley and San Francisco. We usually visit SF and the Bay Area at least once a year both for business and leisure and will definitely avoid staying in San Francisco in the future, if you have a car this is just so much better.
