Usually when a guest has a bad experience, it is because the host is a nasty and dishonest person and doesn’t treat all guests equally. This is a no-win for the guest–if you write an honest review to warn others, they will write nasty things about you. Also, airbnb customer service was absolutely unreachable, especially outside the US you cannot call the 800 number.
I had a bad experience and on return I wrote a carefully worded review that can be confirmed by the messages exchanged on the airbnb system. I knew that she would write something really nasty and untrue which she did.
What’s a person to do other than never use airbnb again?
