@Benanne0 Worse than losing the Superhost badge is having the cancellation review attached to your profile. It will put future guests off of booking with you, if they see it. It's possible, though less likely as it will only show on your profile, not any of your new listings. One thing you can try is contacting the guest and explaining the situation. Offer to fully refund them, plus their Airbnb service fee and a sum in the neighborhood of $100 (or more) for their inconvenience, if they will cancel. It's worth a shot. You will pay Airbnb a monetary penalty anyway, if you cancel.
