Elizabeth and her husband are very welcoming, we had a really good time sharing about our travels, where we come from, ... They even gave us advices for our trip to Yosemites (what road to choose, what to do to protect us from the bears, ...).
Their house is in a charming typical neighbourhood, and the room is really quiet
It's well-situated : we took the BART to go to San Francisco (about 10 minutes walking and 30 minutes riding) so no need to stress in the traffic-jams.
Thanks for everything!
