Was there between end of Winter season and beginning of summer season (which is a somewhat inconvenient period, unless you exactly know what you're doing, you're well prepared, and you know which facilities are open in the valley). The flat is well equipped (in fact, I seldom had dish washer *and* washing machine with AirBNB), warm, quiet and cozy. We had mountain goats in 80m sight form the flat once. Mazzin is well suited as a base camp for multiple excursion types.
