The city hall said that there were now 3,588 establishments on the platform used to monitor the tax, including 201 hotels and 3,211 private homes.

The municipal tourist tax, which was approved in 2014, began to be levied in January on all tourists staying in Lisbon (including locals) at a rate of €1 a night.

The municipality also told Lusa that out of the €7 million, half a million had been paid by Airbnb, following an agreement between the two sides covering the months of May and June.

Airbnb, an online platform for renting houses and rooms for short periods of time, has been collecting the tourist tax since 1 May and paying it to the city hall every quarter on behalf of its hosts.
