no doubt, @Kenneth61 , renting via Airbnb is running a business, and unfortunately so many hosts don't seem to get that.
Interesting perspective, to only offer the cheapest, such as in sheets and towels, etc. I actually believe in the opposite, but I realize a lot depends on the individual listing: yours has a minimum of 27 days, so you are relying on the renters to do the laundry, to keep the place clean, etc. - and a lot can go wrong with that!
My rental is limited to 4 days, exactly so that I can stay on top of things, do my own washing and cleaning when those 4 days are up. And in case I have mildly unpleasant guests - I actually don't! - then they are gone, and everybody can be happy again. I consciously do NOT buy the cheapest, but offer high quality sheeets, towels, and also amenities such as bath gel, shampoo, etc: I do believe my guests totally get that, and they reward me with respect and treating my place supper good.
So for me, the opposite works very well, and often I have no clue where all the nightmare stories we read about here, come from or originate.It just doesn't happen to me, and I contribute a lot of that to me treating my guests to the best, and they answer in kind.
