I stayed in the Chestnut room for several days. My room, the bathroom, and the kitchen were impeccably clean. During my stay, some other guests held a huge party and made a mess. There was literally blood in the bathroom. But the next day the cleaners came and did such a good job that everything was sparkling.
There are some rules they ask you to follow, like wiping the sink or being quiet after 10pm. Which I have no problem with.
I especially appreciate that they allow you to leave your luggage in the living room for a few hours after check-out. Overall I think this is an optimal AirBnB. Very, very nice.
