There are a very friendly bunch at Siena, and a very quiet airport, so no lengthy waits at the hold or multiple go-arounds.
Stunning countryside but there are draw backs, cost is much like the UK and last year there was no one who had a reasonable command of English.
I holiday there once in a while and am a qualified and somewhat experienced pilot, so the lack of fluent English did not bother me, you will really need to have good communication both in the cockpit and in the briefing room, so look for an instructor who speaks good English unless you can learn Italian to a high standard quickly.
Good luck , I'm jealous.
