MADRID, Jan 13 (Reuters) - Spain plans to raise taxes on

holiday rentals so that they pay "like a business", Prime

Minister Pedro Sanchez said on Monday, as residents of the

country's main cities grapple with soaring rents.

"It isn't fair that those who have three, four or five

apartments as short-term rentals pay less tax than hotels or

workers," Sanchez said at an event on affordable housing in

Madrid.
