We were picked up by a friend/accquaintance of Renato's, who lead us to the apartement, because he wasn't in town. Because it is not possible to go into the quarter by car/taxi. He (the friend) also has a very recommmendabel Trattoria right around the corner. His very nice neighbour helped us out with all questions we had, e.g. she turned on the water heater for us. No problem we didn't speak Italian and she doesn't speak English, but we managed to communicate anyway.
