I agree Robert. That is exactly what my experience has been and the repair (damages to windows, and replacement of linens, extra cleaning and everything else) has resulted in my closing two of my Airbnb properties, the risks outweighs the benefits especially with newer guests.
I also believe that the Airbnb is negligent in adequately addressing new guest education. It is essential that guests, especially new ones, be adequately educated especially around hygiene, and damages to host property.
I would note that in this particular incident, Airbnb has refused to pay for anything except for the replacement of a remote control. No acknowledgement of my two years as a super host, no way to appeal, no independent review in the event of a disagreement.
Hosts just need be aware that in the event of a damage to your place, there is absolutely no host guarantee except for the goodwill of the particular agent handling your case.
