@Chamaine0 You say the cleaning is the same whether a guest stays for one night or a week or more, which I know is more or less true, though not totally (if you've just done a thorough dusting, for example, or washed the curtains or blinds, I doubt that would need to be done again after a one-night stay, a floor mopping job goes much quicker if you don't have to scrub at stuck-on food or sticky spills, and if the guests leave piles of dirty dishes, a greasy stove-top and food spilled in the fridge, kitchen cleaning is obviously going to take longer than if the guest left it clean and tidy).
And it doesn't really make sense to charge a lesser cleaning fee for a shorter stay, as some people are capable of making a huge mess in a one night stay, where others may stay for 2 weeks and leave the place immaculate.
But you could do this- up the price of the room to cover the actual cost of a normal clean you'd do if the guests left no personal messes and left it basically clean and tidy- so for you, vacuuming, mopping floors, changing bedding and towels, cleaning the bathroom, replenishing basic supplies.
Then charge a refundable cleaning fee- you'd have to make this really clear in your listing description and messaging with the guests. And it would have to be clear that it is not open to negotiation- that the hosts reserve the right to assess the percentage of cleaning fee to refund. And sate that if you give a refund, it will be given 15 days after check-out, to avoid someone leaving a bad review as retaliation because they didn't get the refund. Then have a very precise list of what guests need to do to be eligible for the refund- in a house manual and posted somewhere prominently in the house.
Example:
If you are interested in being eligible to have your cleaning fee refunded:
All dishes, pots and pans and kitchen utensils well-washed
Stovetop and oven left clean
Kitchen counters and table wiped down
Used towels hung up, not left on floor
All garbage in bins
Fridge clean with no food left behind
Bathroom tidy, counters wiped down
Any spills on floors or furniture wiped up
Your list may vary, but this could be a way to appease guest complaints about a high cleaning fee, reward really clean guests, as well as possibly making your cleaning job quicker.
