I’m very sorry to hear about your difficulties. I can only imagine how frustrating and difficult it must be for you.
Still, I think that there are things that you can do, even when a guest lies.
The best thing you can do is to get out in front of it. There are a number of ways to do this First, by being careful about meeting and greeting each guest. In my case, I live and work at my home and am home for most of the time that my guests are here. It’s hard for them to do anything that I don’t know about.
Also, however, I would work hard in a difficult situation like that to be very quick to contact Airbnb’s customer service people and talk to them immediately about any concerns. Document everything by doing all communications through the app, and then get on the phone with them immediately to advocate for yourself.
If you don’t, and if the guest is the only one talking to Airbnb, you will have to play catch-up, which can be difficult.
I realize that I know nothing about your situation and all the extenuating circumstances you’ve had do deal with I hope my comments are not just stating the obvious, and maybe you’ve already done all of this. I certainly don’t mean to imply that you haven’t. I’m just trying to be helpful.
I myself have not had to deal with such difficult issues, but my own experiences with Airbnb have been positive. In all cases I was able to contact Airbnb before or essentially at the same time as the guest, so the guest didn’t have a head start on me. And I don’t think my guest was lying about anything. So that’s a real problem.
I think you may have a chance to rebuild your Airbnb business, as well. I’d be interested to hear more.
