WOW, very complete Gianlu, thanks , i want to return to the far east of the world (not only Japan) but my girlfriend wants to go to Europe...and like a democratic couple we are, its her turn .
Italy and Spain are very sure visit for the most part of us are descendants from both countrys, Venice is a "duty" because is what she wants more (i really dont), Florence is hardly recomended for some friends, it will be interesting to visit some city from the south of Italy, i really dont know that you are from the south, if we go to there, i will inform you previausly if we go to there .
For the rest of Europe your "city of your dreams" is one of my priorities, i want to visit too Dublin, Berlin, Prague and Wien of thats list for sure, dont discarding the rest of course.
