We stayed at Yumi's place for 4 nights.
This was our first airbnb experience and overall it was a really good one.
It is important to understand that the place is more like a hotel rather than a home, and it has a beautiful kitchen and 6 private rooms that some has private bathrooms and the rest is shared. Our room had a shared bathroom with another room which was ok, but on our second night one of the other bathrooms was out of use and we had to share ours with more people which wasn't so comfortable.
Another thing was lack of toilet paper.
Besides that, we would recommend this place to people coming to tour San Fran, it is perfectly located in a very nice and safe neighborhood , walkable to almost all touristic attractions.
