There was a good article in the Wall Street Journal a few months ago:
"Welcome to Your Airbnb, the Cleaning Fees Are $143 and You’ll Still Have to Wash the Linens":
From the above link:
>'Last month, Amanda Morari spent her sister’s bachelorette weekend at a lakefront cottage in Ontario province. The washer was out-of-order and the vacuum wouldn’t charge so the women spent their last day “wetting paper towels and wiping the floor,” she said.'
>'The host told her not to worry about it, Ms. Morari said, but then came the unexpected: she got a three-star review because the cleaning wasn’t up to the mark. Her perfect five-star rating dipped to 4.1.'
