Does anyone have experience with schools in Italy (or elsewhere in Europe) that offer short term classes in art, language, or history for English-speaking adults? I can find all sorts of schools that cater to college-age students, but I haven't found anything for older student-travelers.

Ideally, I'd like to spend 3-6 weeks taking classes for part of the day with lots of time to travel independently on weekends, and I'd like to be with a mixed age group (i.e., I don't want to be twice as old as everyone else in the class).
