In fact, Pula is one of the most romantic destinations in Croatia - besides being rich in history. I don't know if you managed to visit Split. It's not like other cities in Croatia - it's more like a resort town, but it's really amazing, иt feels alive but calm most of the times, haha. The beaches are clean, the nature is great. I say that because I see you like the country, haha.
