Bella Vita Homes is a very nice private room stay. We slept very well and enjoyed being so close to San Francisco (about 20min) and from the grocery store/mall/movies and only 10 min from the airport.
Please be aware that there are very specific rules that are put in place, including a specific cooking time, use of laundry (which for us was too late in the morning, we wanted to leave the house for tours earlier than the times designated) and cooking/cleaning instructions. The house is also only heated (during our stay making our room very toasty, we opened the window of our room to accommodate).
