Spain's government is cracking down on short-term holiday rentals without proper licenses, investigating platforms like Airbnb and Booking.com, a response to locals feeling priced out of the housing market. Concerns over high rents due to gentrification and landlords favoring tourist rentals are driving this action. Barcelona plans to phase out all short-term lets by 2028, causing debates about expropriation and legality. Protests in cities like Barcelona highlight the challenges faced by seasonal workers finding affordable accommodation. The government aims to create a registry of holiday rental properties to limit listings and may extend regulations to mid-term rentals, addressing broader housing affordability issues in Spain.
