s2h, Varese area, closer to Malpensa, could be a suggestion:You can find lakes, hills and mountains all around, snow is within one hour, for your kids you have an International school in Varese, rented an appartment stays within 900€/month, and if You like outdoors you can find nice single villas in the sorrounding. People are kind, the area is quiet, the Swiss border is within 15 km.
Have a nice stay in Italy.
