1. Go to local Ajuntament and fill in the form for licence application (HUT = habitació d’us turistic), pay the registration fee.
2. Processing takes a couple of weeks
3. Once you have your licence number (HUTG1234 or similar) you go to local police, fill in a form, and get a login to the website for registering your guests.
4. Ask all guests 16+ for their passport or ID card number. I take photos of the details page when they check in.
5. Login to police website and register each guest. Takes 5 minutes.
6. Add your licence number to your airbnb listing.
Tip: I don’t ask guests to pay me the tourist tax (45c per night), I just say that it’s included in the rent. Faffing around with coins is not going to create a good first impression.
