I have been working in the language sector for many years by now and i have always wondered if it is possible to learn Italian with dedication in Florence, especially in the Summetime.
Well, it is definetely possible even though the circumstances are really difficult. There are many things to see and especially at night many events to attend to: parties, aperitives and concerts. And, of course, to enjoy especially of the night life of Florence using alcohol (not a very good idea :-), especially when you pay for an Italian language course).
Recently, i have experienced a week in Florence among students and i must say that it does not help, at all, to drink beer and wine all the nights. Students wear them out and eventually they do not learn any Italian.
That s my idea i will write a more focused opionion tomorrow, CIAOOO
