Earlier quoted context omitted.
Did you rent the flat from AirBnB then? I'm not understanding your comment.
Why the down vote? seriously? I am asking for clarification because I am interested if you were speaking about the upside or the downside? Its not at all clear.
The thanks to AirBNB was as an aside. I think we rented AirBNB but to be honest not sure; might have been one of the many other under the radar holiday house schemes available in Italy and other places.
However the phenomenon under discussion clearly makes something like AirBNB possible -- and good luck to them.
Whether it is an upside or downside overall -- I do not know.
