Hi Em, Firstly you write a correct review to alert others without being too specific, something along the lines of....."This guests unfamiliarity with the concept of home hosting made him difficult to host. I wish him well, but would in futute decline an invitation to host him again!"
That says it all Em, there is no need to be more specific than that, and there are no grounds there for Airbnb to remove that review if he should object.
In all probability he will not leave you a review! People like this do not have a lot of respect for the review system, and if he got his way as far as the way he treated the accommodation and you then he possibly has nothing to really complain about that warrants the time involved in writing a review....If he writes a review at all it is highly unlikely he will write you a good review so you can just say....."I did not find this to be one of my better hosting experiences, I value guests feedback and will take on board what this guest has mentioned but I would not really wish to make any further comment beyond that"!
By doing this Em you are not getting into a vebal fist fight with the guest, you have not accused him of being anything other than a pain in the a*se....but the main thing is you are not drawing attention to what could possibly be a less than flattering review so it will slip into obscurity in no time...people just won't take any notice of it like they would if you had a major 'he said/she said' stouch over this hosting. Allways remain dignified and don't give the guest anything to resent about you!
Cheers.....Rob
