I'm a host.
I write because I'm deeply disappointed with Airbnb in the way it handled the following situation:
I had a reservation (2 adults) expected from 1.11.2019 to 20.12.2019. After 15 nights, guests organized a party of about 30 people until 1:30AM, grossly disregarding house rules that prevented visitors and parties. As a result of this, and because the neighbors were very angry and threatened, I had no alternative to forcing guests to leave the house immediately and permanently, always in contact with Airbnb. Airbnb followed its policy, withdrawing from me the amount for the following nights, which was returned to guests.
Thus, the guests, in grossly disregarding the known rules and also unacceptably disrespecting the neighbors and the law itself, were not harmed in any way as they could simply use the same amount to relocate on the very day of departure. I, on the other hand, that had no fault that this happened, lost the money for the following nights and got the calendar unlocked, in November, not being able to make new reservations to cover the lost money.
The Airbnb supervisor's response was that Airbnb cannot (by law) withdraw money from guests from following nights to hand it over to the host when the cancellation originates from the host (even if it is the fault of the guest) and that Airbnb, in this particular case, was not unwilling to compensate me for budget reasons.
Unfortunately I conclude that the policy is wrong and that, even if Airbnb cannot (by law) withdraw money from guests to hand it over to the host, it must assume that expense for the host. I feel that, in my case, Airbnb simply did not want to compensate me, which means it agrees with this policy, because budget certainly is not the problem.
What's more, even worse, I think the image that Airbnb is giving to guests is that it's okay to break house rules in any booking because they get refunded and can continue to book through this platform.
