A little beggar here, will want to go to this one, but cant find no-one who is available in my home town to do this. Just found a perfect 2 day route for me to do this:
Tallinn-Milano Bergamo 25.nov
Milano Bergamo-Sofia 26.nov
Sofia-Milano Bergamo 27.nov
Milano Bergamo Tallinn 27.nov
So is someone perhaps going through Milano aswell, cause it would be pretty boring to travel alone
