If it's the Dalmatian coast - Dubrovnik, Mljet, Split, Brac, Hvar, definitely.

If you stay in Istria, Pula, Rovinj, Brijuni islands, and the inner part of the peninsula with 7-people cities on small romantic hills (Hum, Roc etc.).

I live here (actually in Zagreb, the capital), so let me know if you need any help or have any questions!
