Thank you, I see the logic of turnover expenses and that even a one-night guest can leave a mess. But a one-week cleaning is much more thorough, with every corner dusted and cleaned, and every blanket washed. And for a one-month stay, I clean every week.
It may be that the short-stay cleaning fee feature is most useful to hosts like me who have a humble room available for a low price. In this case, a one-size-fits-all cleaning fee becomes, percentage-wise, prohibitive for someone staying just one night. I would still like the opportunity to try it.
