Staying with Zoe is absolutely wonderful. I was there for 6 weeks and loved the atmosphere and surroundings at the house. You feel welcome as soon as you arrive and she is always smiling and happy for a chat around the kitchen table.
If you want to rent a place in the Bay Area with calm surroundings, sunny weather and still be close to BART so you can be in Downtown Berkeley in 10 min or Downtown San Francisco in 30 min this is definitely the place to stay :)
