@Branka-and-Silvia0 AirBnB charges services fees on the cleaning fee to both guests and hosts.
Host service fees
The host service fee for homes is generally 3%, but may be higher for hosts in Italy or hosts who have a Super Strict cancellation policy. This fee is calculated from the booking subtotal (the nightly rate plus cleaning fee and additional guest fee, if applicable, but excluding Airbnb fees and taxes) and is automatically deducted from the payout to the host.
Guest service fees
The guest service fee for homes ranges between 0% and 20% of the booking subtotal (the nightly rate plus cleaning fee and additional guest fee, if applicable, but excluding Airbnb fees and taxes) and is calculated using a variety of factors—these include the reservation subtotal, the length of the stay, and characteristics of the listing. In general, the service fee gets lower as the reservation cost gets higher. Guests see this fee on the checkout page before they book a reservation.
