It's a scenic drive indeed, with much different cities and landscapes to see!
You have catholic villages with colourful lit churches - and then in the next village you have communist red flags, that's very funny. And you have different vegetations, flat land, hills, sea - very interesting. I would highly recommend doing it once!
Important: You definitely should opt for a car with driver! It's a 7 hour drive, so you should start at 9 or 10 in the morning.
