The house in San Francisco was very nice and the host is very friendly and helpful.
The room itself is okay as well and has everything you need (coffee machine, fridge, mirror and a comfortable bed). It was also very clean.
The only thing we didn't like was the fact that you do not have any daylight and if somebody uses the kitchen, the smell comes up to your room.
The bathroom is to be shared with max two other guests. Maybe it was because of the others but we were a bit disappointed of the bathroom because it was not clean. There were hair everywhere and the bathroom was not cleaned during our 3-day-stay.
The area was silent, safe and nice.
