As a former CPL/ME/IR student, I can say that Bartolini is a good choice if your budget is limited. You will get for an excellent price, a modern fleet, not the best ME, but good enough to learn. Of course not everything is excellent, their sim instructor is useless, an excellent person but a very bad instructor. Sometimes you need to push them to schedule you and the difference between isntructors is huge, with some you feel you are learning with some other you are just flying by yourself. I personally think that at the end of the course I was ready to pass the skill tests but not by an extra margin.
I think Bartolini has a good vision but it still needs to be improved to become an excellent flight school. Anyways as I said in the beginning if your budget is limited, Bartolini is a very good option, if your budget doesn't have limits and you want a better preparation, go somewhere else.
