The pressure on rental flats in many towns is massive. Young people and families, key workers, etc, can't afford to rent but worse than ever, can't find anywhere to rent. Why? Because landlords have decided to rent for much much higher returns on RbnB- and do not follow the rules, do not respect neighbours, and do not pay proper tax either, which represents huge unfair competition on Hôtels and other holiday rentals.
As Aveline has said, many Councils are looking into tightening regulations, registration and get those to pay proper taxes.
So on the one hand- there is suitability for travellers, and on the other ... well the other side of the coin.
