We had a great time in Torre di Mactheus Petraro. The house is very good located and very beautifully decorated. Although we met Michele at the very end of our stay, he was ready to help at any moment. There was a variety of information booklets in the apartment and a welcome drinks in the fridge. Our main comment is the heating of the house. As there are no doors, the kitchen and the living room were always cold, and the sleeping areas (the 3 floor) very warm.
The other note is that from the description and the photos, it doesn't become clear that the both double beds are actually in one same space (although on different floors). We enjoyed our stay and would come back to this art apartment and the beautiful Giovinazzo.
