Overall we loved our stay at this Airbnb. A beautiful apartment that is perfectly situated and very clean. The big issue we had, however, was the lack of ability to contact the host when their office was closed. The main number on airbnb doesn't work, and so when our key didn't work we really didn't know what to do. Apparently there's an emergency number at their office which they don't publicize elsewhere.
The rest of our stay was great however! We loved being there... And Cadaques is a wonderful destination.
