Luca's place is wonderfull and just as described. It is located in the upper part of the town so it is very calm and quiet. The town is the starting point for several hikes and other hikes in the area are easy to get to from Piazzatorre. Also Passo San Marco can be explored from there. In the appartment some maps are provided.
We didn't have the pleasure to meet Luca in person, but he was very responsive and arranged for Gloria to meet up with us to let us in.
