Protest organizers said up to 150,000 people marched for affordable housing, but the Spanish government gave a much more modest estimate. The protesters are angry at companies such as Airbnb and Booking.com.

Tens of thousands of people protested on Sunday in Madrid to demand more affordable housing amid rising rental prices as Airbnb and Booking.com dominate the short-term rental market.

Under the slogan “Housing is a right, not a business” people marched in Madrid, calling for lower rents and better living conditions.
