Naples not the cheapest but planes in pretty good nick and you get the visa which you apparently need. Also you fly from a controlled airport which is good training
Brit is a very friendly school but the planes have seen better days but they are pretty cheap.
I have flown at both schools and the choice really brakes down to cost and Naples is a bit more upmarket than Winterhaven (red neck central) to stay in. But if you are doing a 21 day ppl you don't have much time to party. Although its not unknown for George and Jatin at Brit to show the students the local drinking establishments at the weekend.
And no query neither school is paying me.
