We reported the host to the animal welfare authority! He had a dog chained outside the "castle" during the whole time we were there. According Italian law a dog can be chained for max 8h. The dog was sick and had lost a lot of fur and it was apparent from it's behavior that it was badly treated. When we confronted Riccardo about this, he said that the dog is 20 years old (which is not possible for a dog of that size to become so old) and he couldn't have it loose because it would run away. He told us this trough google translate since he only speaks Italian.
Apart from the dog; the room we got was not the same as in the photos. The one we got was very bare and had no view at all (big tree outside blocking). There is no wifi in the room as advertised, only in the dining room.
