@Ben4524 @Kate867 There seem to be a large number of dormitory style listings in Paris. Many appear dodgy as they regularly change the listing name to 'lose' their bad reviews. This listing does seem to go one step further and not actually allow people to stay. I can't for the life of me figure out what the concept is. Perhaps it is some sort of immigration scam?
I don't see how the expenses scam works as the booking receipt will specify the cost which is surely all the guest can claim.
I do agree with Kate that Airbnb needs to look at these types of listing.
