An interesting article on how tourism, in particular the explosion in AirBnB and other holiday lets, is ruining Naples.
The same issue can be found in cities across Europe and it's one of the reasons I no longer use holiday lets. It is no longer confined to people renting out their property for a week or two whilst they go on holiday but far more likely to be investors who have brought up property for the sole purpose of renting it out to tourists instead of it going to someone who needs to live there.
