First time I’ve had something like this! Of course they had no intention of staying at my home, the enquiry immediately launched into a long discussion about an event being held in New York and they’re seeking donations. More talk about the background of the charity etc etc. Basically just another sneaky way of canvassing for donations, as if we don’t get it enough via email, telephone, door knocking, tin rattling as we’re trying to go about our business at the shopping centre etc.
Just hitting decline isn’t enough, Airbnb requires that you give a reason for declining. I just put a full stop in and that progressed the decline action.
