We stayed in this apartment with our 6 kids and had a wonderful few days touring the beautiful Val di Sole and surrounding areas - Brenta Dolomites as well as the del Stelvio park. Mestriago is a quiet residential town, set in the valley, a short car ride to some of the most beautiful scenery, hikes and activities in this area. The Male Flying park is a short ride away, and there are many options for hiking, biking and rafting within a very short distance. Mestriago is at all busy like the more 'touristy' destinations (e.g. Madonna di Campiglio) and certainly quieter at night - but it has all the necessary amenities within short distance - supermarket, tourist office, gas station.
The apartment was well located, clean and functional and had just enough space for a large family. Claudia was very communicative and answered any question very quickly, both prior and during our stay. Marta (co-host) lives and works close by and was on hand for any questions/issues (there were one or two minor ones - like no wifi/sketchy internet and a minor electrical issue). All in all I would recommend this apartment for a family on a budget who want a central location to enjoy this fantastic beautiful region.
