We stayed in Arianna's chalet in mid January and found it perfect for our needs. Very cozy, a great open fire with enough timber provided for our whole stay, heaps of random toys for the kids and plenty of bits and bobs in the kitchen which were appreciated.
We went fairly far afield each day (lake Garda or Verona) as not a heap in the area was open in winter but in summer i imagine there would be plenty to occupy closer to the house. Also, the lovely outdoor areas will come into their own in the warmer weather....unfortunately we missed out.
Definitely worth considering, many thanks Arianna
