Barcelona is one of Europe's top tourist destinations, which has also made it increasingly expensive to live in. Rents have risen nearly 70% over the past decade.

Following months of protests against mass tourism, the city's mayor, Jaume Collboni, announced plans to ban short-term tourist apartment rentals to tackle the affordable housing shortage.

But will that fix Barcelona's housing crisis? According to the city's owners' association, short-term rentals comprise just 1% of all residential units.
