@Ute42 Obviously, the guest is likely to leave a bad review, this is blackmail, and you can not negotiate with terrorists and Blackmailers, you will still lose.
@Debbie-And-Arnulfo0 Imagine - Four Seasons, Hyatt, etc...In the evening, the neighbors were noisy, you complain about the reception, and?will you be offered monetary compensation? Never) In the best case, the Manager will give you a coupon for a massage, and the guest will be happy about it, like a child who received a candy.
Given that Airbnb is not just a formal platform, like booking com, but a certain relationship, it may be worth telling the guest that you are upset with this incident, which in no way (!) didn't depend on you. And bring a $ 5 bottle of wine instead of $ 75 money and still be so worried, it's basically wrong, IMO. Guests sometimes poop on our heads, sorry, and such compensation corrupts them even more.
