Overall, very great! Sarah was an amazing host!
One thing that I would like to comment on for future guests is that this house is not actually a house for a "single family". There are two different addresses in one house. It seems that Sarah's family uses the first and second floors, and the semi-basement floor is occupied by someone else with a different address. And there is one door in the unit (right next to the bathroom in the picture) that is directly connected to the semi-basement unit. I could not lock that door, and the someone in that unit can lock and open it. He did not bother me at all, but I did not feel 100% safe because of the fact that this unit can be accessed by someone who is not authorized by Airbnb.
Besides this, Sarah's place is very great!
