@Lara1189 It's incredible how easy it is to make a phony listing - many homeowners have been puzzled to find an Airbnb listing made out of pictures and specs cobbled together from old real-estate ads for their homes, often not even in the same part of the world as the actual property. A reverse-image search can sometimes yield clues.
I can see how this experience would put you off using Airbnb again, especially considering how hard it is to reach customer service in an emergency. But for what it's worth, some listings are a much safer bet than others. If you see that a listing has been established for a long time, has consistently great reviews from real people, a host with a complete personal profile and visible face photo, no host cancellations, and a price that isn't "too good to be true," you can book with reasonable confidence that it's not a scam listing. A new and unreviewed listing can also be totally legit, but based on my experiences I wouldn't personally book one again.
