The probability of people being positive is why I am concerned. My property is designed for groups of friends and extended family reunions. (Its a 7 bedroom property) So the odds are that one of the group is either positive or knows someone who is positive.
Even if they don't just ask a friend who is known positive to furnish them with a positive test result, there is enough information out there on ways of generating a fake positive Covid test.
Welsh Government is still offering free lateral flow tests, you can't pick them up from shops, they have to come mail order, but you can still get them.
So while Airbnb is continuing with this policy of offering a full refund to guests if a single member of a group claims to have Covid, I effectively have lost all control on my cancellation policies if I take a booking via Airbnb.
I agree if they are waiting to change policies world wide we are going to be in for a long wait, but I would have thought that changing policies for Europe, would have been practical.
