Italian language schools in Italy.

I will tell you that I am also looking for a suitable school because I would like to enroll my son

Is there a particular area of Italy that you are interested in?

I highly recommend Madrelingua in Bologna and ABC School in Florence.

I do my online studies with Madrelingua of Bologna.

Lingua It if you are in Verona!

My husband really enjoyed 5 weeks of morning and afternoon study at the Istituto di Michelangelo in Florence with students from all over the world: https://www.michelangelo-edu.it/index.htm

Thank you all for your suggestions.

As I recall, there's at least one Italian language school in Orvieto, should you wish to study in a smaller town that's not too far from Rome.

You might also look at this school in Assissi - https://aliassisi.it/en . I stopped by there one day and was very impressed by the people I spoke with. That's also reasonably close to Rome. They have a variety of on site and online programs available, and also have options for student accommodations and other assistance for students studying at their location.
