@Jack1880 I hope this experience hasn't put you off old-school Airbnb hosts or the lovely people of Malta. Rather, what you experienced was a really non-bright person trying to run an improvised property management company with a listing platform she couldn't get her eighth brain cell around.
One way to spot the warning sign of this in the future: look at the fact that this host has 345 reviews, but the sum total of all her active listings' reviews is under 100. That is always a surefire sign that she's deleted and re-animated some listings. The only reason a host would do that is terrible ratings. Now look at the existing listings - obviously there are several duplicates that are exactly the same property. But read the reviews - despite the host's best efforts to suppress her terrible reputation, even the new listings are getting a mixed reaction at best. All the information you need to know that this is a disreputable and untrustworthy host is actually right there in plain sight, if you know what to look for.
Next time, I recommend choosing hosts who show some consistency. A profile with 300+ reviews shouldn't have a smattering of listings with just a handful.
