Hi,

I hope you didn't take the job. The fact that three people have already written bad reviews about this school, should send alarm bells ringing. I also worked there. Don't let this discourage you. There are lots of schools in Italy to choose from. An idea is to ask the school if you can email one of the teachers to ask what it's like to work at the school. If the boss says no, then that is a clear sign not to take a job.
