Especially in the big cities of Italy – Rome, Milan, Florence and Bologna – it has become almost impossible for low earners, young families and students to find affordable housing. The lack of affordable housing has been considered one of the main reasons for the record low birth rate in the Bel Paese for years. Students, in turn, are drawing attention to their difficult situation by camping in front of universities in protest. The reason given for the shortage of living space is usually the sharp increase in the number of short-term rentals (mainly on the Airbnb platform); In Rome alone, almost 20,000 rooms and apartments are offered on the portal. As a result, these are of course missing from the housing market.
