We stayed at a room rented by Siegel.
The tub was very clean.
The toilet was very clean, but there was a scape of the sewer of the really old building. So it was smelling so bad, that it was difficult to stay in the toilet room and the smell bleeds to the bed bedroom area.
There is a list of instructions for you, including don't tell any neighbor you are in an Airbnb if they ask.
Removing all linen.
Keep window blinds down.
Ventilate bathroom after shower
I think price might be because of location.
