I have been staying at Kai's place for 3 nights. In general, the room was clean and tidy. Second, it is close to the city centre.
One thing, which I think is important, is the self-discipline of the other housemate. As expected, the kitchen and dinning area were to be shared among housemates. As such, the hygienic condition of the kitchen was our collective responsibility.
As requested by the host, one has to clean up immediately after using all kitchen stuff. However, I saw used spoons and forks in the sink, leaving with some food remains. That does not seem welcoming to other users, especially when you see some food remains in the sink.
Luckily, the host has employed a domestic maid to clean up the room, helping to mitigate this problem.
This is my first time to try airbnb. Concerning the manners of other roomates / housemates, it is sometimes a matter of luck.
All in all, Kai's house is good.
