It's been great so far, and if you're backpacking, these are the cities I'd recommend: - Prague - Budapest - Bratislava - Ljubljana - Kotor - Berlin CROATIA: - Zagreb - Hvar - Split - Dubrovnik ITALY - Turin - Rome - Florence - Cinque Terre I live in Berlin now, and travel to new European cities every 3 months. So if you need any more suggestions and tips, inbox me anytime :) Cheers, Riya
