Great space! Looking to save a little in San Fran as everything is so expensive. This unit shares a bathroom and a half with 3 other bedrooms, 2 of which being other AirBnb guests, one is a long term rental. There were a couple of times that we needed the shower and it was occupied. If you decide to stay, remember there are other guests while you are using the shower (TAKE A QUICK SHOWER!) Exactly what I expected. Thank you Asok.
As far as the cigarette smoke, there was an odor there when we arrive but it was only for a couple of hours, then we didn't smell anything.
