A lovely house and a great base if you want to explore the bay area.

I stayed at the house for three weeks with my wife and four young children. The house was spacious enough with its three large bedrooms. The veranda is a great place to hang out and the kitchen/ dining area is also a great place to gather (barbecue available, but we did not use it). The kitchen is fully equipped and the local grocery store is 5 minutes away, as it the local Walter Haas playground. We also had access to a washer/ dryer. Wifi was also available.
The house has off street parking. I advise hiring a car to get around as you can be in downtown San Francisco in 10 - 15 minutes. Alternatively, there are bus stops nearby.
The micro-climate in the hilly areas of outside SF means that it can be colder and windier than it is in the city. When the weather is good though, the view of downtown SF is beautiful.

Bruce is a great host, easy going and very generous. The kids loved the pastries.
