I am an experienced host, and you have misunderstood what I am trying to communicate. I have had many guest staying for months without problems both through Airbnb and other sources. In a small apartment, when someone is staying inside the room 24/7, it affects the host, not being comfortable at home. I do not expect guest to be out all the time. I had a guest for 6 weeks, and the person sat by the kitchen table for 13 hours a day, 50 cm. from the stove, and I had to relate to that for every cup of coffee and meal I made. I am talking about behaviour that is a bit "off" for a longer period.
