Great place, close to BART station, big room, very clean and close to good points in San Francisco.
Jason wasn't in the city, but his mom made my check-in, explained some questions I had, showed me some markets nearby. As they don't live in the house, she gave me her number and said I could call her anytime I needed.
I have nothing to complain about my stay and if I visit San Francisco again, I would probably deal with Jason again.
