Ich bekam gestern eine verbindliche definitive Bestätigung von @Max7 Aussage, dass der SHS nicht flöten geht, direkt vom Support:
"Thanks very much for tuning into our 'Behind the Scenes of CX Webinar' and for submitting this question!
As it stands right now, if you choose to cancel a reservation because you are uncomfortable with a guest and indicate as such when going through the cancellation flow, the reservation will be recorded as cancelled without any penalty and will not affect your Superhost status.
If you are realizing the need to cancel within 24 hours of check-in, you will need to contact us instead, but we will abide by the same policy.
I hope that clears things up a bit. I'm looking at the article in our Help Center now and realize that it does state this explicitly. I'll make sure to report that and hopefully we can add some clarity for other hosts with the same question.
Thanks again Till and Jutta. I'm glad to have as members of our community!"
