We stayed one week in Xino high up in the mountains and we had a great time :) The neighbours are friendly and there are many places you have an amazing view to the lake. In Fonteno is a small shop for the most important things and a nice bar. We recommend the pizzeria in Solto Collina, the pizza was so delicious. There is a trail from Xino down to Riva di Solto but it takes about one hour. Cristina is a nice and helpful host so thank you for everything.
Best wishes.
