As a host should I be concerned about the new "Get-What-You-Booked Guarantee". I have a great place and I pride myself on the maintenance, but it's easy to see how a one "bad apple" guest might claim days after the stay has ended that the ice maker wasn't working, and even though they never contacted me about the issue Airbnb will issue a refund. Is that how this works? Who determines if a refund is being issued and is there an appeals process? I keep looking for clarity, but can't seem to find it.
