Carol is an amazing host, one of the kindest person you will ever meet. The house in nice and cosy, the bed is comfortable and the area is safe and close to many cool shops. Commuting to the centre is also very easy as the bus stop is 2 minutes away.
The room is not super bright as the windows face the building just in front of so it doesn't get much sun, but it is spacious and comfortable so that was really nice.
The only small issue I had with my stay was that the pressure of the shower was quite low which to some people might be a bit annoying.
Overall, beautiful stay and would definitely recommend Carol's place if you are visiting San Francisco :)
