In Florence, it is possible to take an Italian language course even for one week. You can enrol with no notice, just drop in and start the day after, even if you are not interested in the language. It is a good way to get to know other people. To have a guided visit to museums and interpretive walks included in the price, to use computers and other services is a small fee or included in the course price. Some schools also can organise accommodation on very short notice.
