My flight into Lisbon was delayed by 24 hours, when I got in I would have had just enough time to shower and relax for a bit before check out time. But the host never provided the code to get in and didn’t respond to my requests to get the code, until finally the day after I was supposed to check out. They had apparently sent the code via an external messaging app that I don’t use. I had no way of knowing so was never able to access or use the Airbnb at all. When I politely explained this and requested a refund, they refused. Very disappointing and frustrating experience, especially after having spent the last 47 hours just getting to Lisbon.
