Hoping to spend a weekend in Italy in September. Arrive fri evening, leave Monday morning. Family of 4, kids 11 and 13. Looks like we can fly into Pisa, Venice or Milan MXP. Please help me find a beautiful, picturesque and typically Italian destination for a short, family weekend away. Ideally accessible by public transport and outside the city. I've never been to Italy to start and would appreciate some pointers, thank you!
