The place is perfect, just after the tunnel and simply turn first left and heading midway in the street. The same road eventually leads to cala rotonda. We just fell in love with the beach as we only realised now what beautiful caves it offers.
The casetta we stayed in offers a bike parking but if you are renting a car they have an alternative parking place round the corner of the same property as the street is too narrow to park a car outside.
Everything was as described on Airbnb. We cooked very easily and enjoyed every single day at our stay. The place is highly recommended and Guisy was so welcoming. She picked us up at the port and showed us the way to the apartment.
