After a long day exploring Naples we return to our apartment for an afternoon siesta, when we thought we heard a knocking on our door to which we ignored. 5 mins later we heard a very loud and aggressive knocking on our door, followed by keys starting to unlock our door. I got up and confronted this person, which turned out to be our host wanting to show people though our apartment while we were staying there without our consent..This is absolutely unprofessional and I still cant believe it happened. Very unnerving thinking our host could have been in our room when we were not there... would not recommend...
