We had a wonderful week in Sarnico. Fiorenzo was a perfect host, accommodating, friendly, quick to respond, and was a good source for information about the area. The apartment had an amazing view perched above the lake - the photos are accurate. It's a nice 30 minute walk to the town center or 10 minute walk to the supermarket which we found to be the best in the area.
The apartment was immaculate with every amenity promised. Fiorenzo supplied us with items we still needed - clothing iron, bottled water and even air conditioning - which was not originally included in our rental.
I would highly recommend this quiet little piece of paradise on lago d'iseo.
