I've had nothing but wonderful reviews, people love the place. Now we have our token "picky guest" who began messaging us with complaints of how the house did not meet their cleaniliness standard. Within a few minutes of their arrival the wife had actually checked the ledge above the shower wall for hair, and alerted us that she found some hair up there. From having challenges connecting to wifi (our housekeeper came over to the house and helped them), to having a hard time finding sheets for their extra guests (they found them), all the way to messaging me to say we need to talk to our housekeeper about what kind of job she's doing, etc.
They've "attempted" to send us pictures of this atrocious mess they are having to stay in, both through airbnb messages and through direct email, yet we have not seen anything.
They've contacted airbnb saying they had an emergency and for us to contact them immediately, but when I ask him about this, he doesn't answer my question.
Now they are asking for a refund of their housekeeping fee.
How can I protect myself and what should I do?
