Amazing place. Clean, convenient and optimized for a speedy checkin. This is hosted in a traditional SF row house, and has single pane windows, so there is a bit of street noise as other reviewers have mentioned. The hosts identified this and include ear plugs with your stay, which work great. Also, since central air is rare in SF, a large fan is in the room so you can circulate some air. With your ear plugs in, the fan noise is minimal. The best lodging per dollar in the city, bar none.
