Hi @Sophannara0 Airbnb charges host for cancellations if Hosts cancel a reservation from their side. If the guest asks you to cancel the booking on their behalf and you agree to do so, it is considered a cancellation by the host. In this case, you might be subject to penalties, such as Loss of income for those booked dates and a Cancellation fee. Did you receive a cancellation request from your guest?
If a guest requests a cancellation and you want to avoid penalties, you can encourage them to cancel the reservation through their Airbnb account. This way, the cancellation is on the guest, not you. Hope this helps!
