Sorry I can't agree with @Clara116
If I had been in your situation @Lofty0 if the guest wasn't happy with the temporary air conditioning I would have asked Airbnb to cancel the booking under extenuating circumstances, as the guest was not happy with the solution you found. It would then be up to Airbnb to work with the guests to find an alternative.
Who brings two suitcases of whisky on holiday with them. I think you are correct they are looking to create problems.
I would leave an honest review for these guests, saying you did your best to resolve a last minute problem with your air conditioning and that the guest wasn't happy with the temporary air conditioning and accused your Muslim business partner who doesn't drink alcohol and who has provided maintenance for you for five years with stealing two suitcases full of whiskey.
You are an airbnb management company with multiple properties so much more experienced than most hosts on here including myself. I am sure you know that some guests are more difficult than others. The important thing is to leave an honest review and remain professional.
