same in Italy. Nobody wants to rent long term anymore and lose the apartment to someone who can't pay but can stay for a year or two.
I personally met owners who had to pay gas, electricity and water to a tenant who didn't pay rent for 3 years.
As soon as she left they went on Airbnb and didn't look back.
Managing an Airbnb is not simple many people would prefer a long term tenant but it's just too risky.
