Italy (generally speaking) only fits the sunny one of your criteria...(and at the moment we are deep in storms, wind and damp)
I am very happy with the Italian education system, happier than I ever thought I would be......but that is because dd is like me, studious, booky, learns stuff in an instant and is passionate about everything. The Italian education system (I am more or less quoting from an Italian MNer who once said this, and I realised she was spot on) teaches you things, facts, stuff whereas the UK one teaches you how to do things and stuff. As a parent you are totally expected to "follow" your child's homework in the afternoon, and if you work, then you have to find someone else to help them.
My dd is 9 and has a minimum of 2 hours homework a night and has done since she was 6. They are regularly tested, and have reports with marks out of 10, and yes, even though it's unusual, it would not be unheard of for a child (even at elementary) to fail a year and have to resit.
For home birth options you would 100% need the north. Here in the south 60% of all births are C-sections. Pregnancy and childbirth generally is very very medicalised. Healthcare is good, because most people when they have more than just a run of the mill cold, pay to see someone privately. Dentists are extortionate.
The cost of living in Italy is far higher than the UK. (for general day to day stuff) Food, clothes, utilities, rents.....We pay for a tiny 2 bed flat with kitchen-come-living-room and a shower not a bath, more than what my Mum rents out a 4 bed house with huge garden and double garage for in the UK.
I am that person who uses the quote "I spent so many years in Italy because I really wanted to live in Spain"
so I know where I'd be headed if I had my time again! (I would head west in Spain, forgetting totally the south and east coasts) In my next life I'm living in Salamanca.
