We booked this accomodation for 3 people and the price was 30€. When we booked an apartment, Maria sent me a message saying that the price on AIrbnb is not ok and demanded us to pay 43€ total.
I said ok, and agrees with her, but when we came to the house she demanded us to pay 20€ more to cover Airbnb fee....?!?
In the end we did it.
