it would be very helpful if Airbnb would call it differently because it is not only the cleaning time and cost that counts. It would be less confusion if it's called: short stay fee, or longer stay discount or turnover fee for example.
For an off-site host, every turnover is very time consuming and it cost us money. We have to go to the city around 11 when our guests check-out and then we clean for 1,5 - 5 hours and then we have to wait for our guests to check them in. Often there is no time to go home and back so we stay in the city, drink a coffee in a cafe and eat something in the restaurant and of course, it is not free. If our guests arrive late in the evening then we go home and back 2x in a day, often during the rush hour. Our entire day is occupied and fragmented + here is the additional fuel cost. This is the reason why we accept only 2+ nights bookings (we have 2 apartments)
A cleaning fee also works as a discount for short stays between 2-7 nights.
Your prices are very low so maybe you could raise your nightly price and remove a cleaning fee if 1-night turnovers are not a problem for you.
