From afar, it seems pointless to advertise you cleaning business here, since it's absolutely useless to us, and most others on this forum, because they're nowhere near your 10 sq. Km patch on the planet. Out of 1000 views of your post, you'd be lucky to get >one< anywhere near you.
So, regarding the topic, "cleaning fees" are "problematic", we just hide it in the price.
Yes, laundry and cleaning is expensive. But I've found that people would rather pay a higher per night rate than pay extra for cleaning.
And when they "pay" for "cleaning", they tend to not bother tidying up on departure, leaving the place messy with lots of dirty dishes, don't bother with the rubbish, etc. But if it's included in the price, most will try to tidy up before departure. Some obsessively.
Now, I realise that this probably wouldn't make sense unless you're "whole house" listing. But we are, and these have been our observations.
