Three of us had a comfortable stay at Andrea's. The location is good as it is just a few meters walk to the lake. You can see the church Capanna Santa Barbara lit up at night at the Monte Rocchetta from the balcony. Ducks and swan swim into the open pond which is also a part of the complex. :-)
Andrea's parents Flavia and Cesar were welcoming and helpful with tips on where we could rent via Ferratta gear in Arco. We will come back and would recommend anyone else who wants to stay here!
