We stayed 3 nights and Sergei did take care of us from the beginning to the end! He wrote us before our arrival to check timings which was very nice and gave us some advices. The room is big and really the same as the pictures! Location is around 30min by car from the center of SF but if you have a car it is fine, otherwise transportation is not so far as well. We could park easily in the area and the place is very quiet, we had good nights of sleep.
I found a bit of dust here and there in the room but ok, I am very picky...
