Hello expats! This is my first post here...
What i am wondering from other expats is how did you find a good school for your english speaking children when you moved to Italy and how did you decide international school versus public school? Also does anyone have any information on montessori schools in italy?
I am Australian, however my husband is italian, he has been here with me for the past 10 years however we feel it time to move for a year or 2, for the children to be able to spend time eith his side of the family and to experience italian life/ culture and learn the language.
Thanks so much!
