I have a guest who just arrived for a 30 day stay. His profile stated he was coming from another UK city, and he didn't mention anything regarding foreign travel during the correspondence. Yesterday he texted me saying he was travelling to the UK from a Country X that is not subject to any restrictions. When he arrived today he said he'd spent the past several months in Country X and Country Y, which is definitely on the restricted list and has been since a 14 day quarantine was imposed by the UK It turns out he'd spent the entire time in Country Y and had only transited through Country X.
Tonight he says that he's received an email from UK immigration telling him that he is required to quarantine for 14 days due to his travel in Country Y. He will have to quarantine at his address in the other UK city, which he provided in the travel form he'd submitted. He now wishes to cancel and receive a full refund less fees.
I'm sympathetic but also out a lot of money. I've also been lied to by a guest who did not tell me any of these facts when booking. I'm seeking guidance on (1) how Airbnb will respond to the refund request and (2) what my ethical obligations are to provide a refund. I'm tempted to offer a compromise that I will reimburse him for any days I don't rebook. Thanks in advance.
