One thing to consider do you speak any of these languages (i.e. French, Italian or Spanish) or at least willing to learn?
Just an opinion and my experience of course but I think learning the language greatly helps from meeting new people and to integrating into that country. Of course you could live in a tourist town which have a lot of English speaking inhabitants but then house prices are probably going to be higher and you're probably not getting as an authentic experience
