Sean is an awesome host! The department was exactly as described, with a great location in the center of SF for us to get everywhere. We had a car which we left in a parking lot 2 weeks away for 25$ the night.
We booked the place more than one week before going, and he stayed in contact with us the entire time, helping us plan our visit, giving us reviews and ideas, as well as very useful tips. He even invited us to hang out with him and his friends. I will definitely stay back with him if i visit SF again!
