My son and I stayed in the downstairs apt at Zack's. It was exactly as described, 10 minute walk to the BART and very, VERY clean. The BART makes it easy to get to SF or Berkeley and also is very convenient to the airport. Communal kitchen upstairs is VERY communal in that there are 4-6 people staying there, some long term renters, some airbnb people. It was OK, though I wouldn't have been comfortable actually cooking. People are friendly enough but I felt we were sort of passing through their living space without them having much say in it. A nice touch is there is a lock on the door to the apartment so I felt comfortable leaving stuff there during the day. In many ways a good place to stay.
