I think this thread is an illustration that you can forget the earthy, people-friendly image that Airbnb portrays, and assume that it's just another booking platform. A transactional business.
You can assume that at least some number of guests will be conscientious and respectful, but it's never guaranteed. In fact, it seems in the past few years, there's certainly been a shift toward entitlement and lack of any responsibility. And for hosts, there's always costs associated with that behaviour.
If nothing else, one thing Airbnb is really good at, is generating bookings. It has very broad market reach and has become extremely guest-friendly, which of course, attracts a lot of guests. And that means bookings.
So, leverage what Airbnb is best at...to your advantage.
Given that as the pandemic wanes, the bookings will certainly increase, we should all be aware that it's ever-increasingly becoming a seller's market (at least on Airbnb). By design.
And that means you can probably raise prices to compensate for the costs of declining guest quality, while still staying well booked.
You may receive fewer enquiries, but there's always another one in the queue... thanks to Airbnb. And frankly, our experience is that those that pay more tend to be the least problematic. So perhaps that's another plus.
It was great while it lasted, but unfortunately, today it's descended into just another transactional business. So, we have to run it like one, while attempting to retain as much "earthy humanism" as we still can. Despite Airbnb.
