Yeah Croatia is on my bucket list. And countries like that wouldn't get as much tourism probably from north America or Western Europe as the big tourist spots in Europe.
There's lots of cities or places in the countryside in various countries that wouldn't be visited as often as London, Paris, Munich, Madrid, Barcelona, Rome etc but still worthwhile to go.
I was only in Tallinn for a day trip but it was definitely worth it.
