We flew to Croatia with Ryanair 2 years ago, to Pula. I rented an apartment in a small town called Medulin, not far from Pula. lovely place, eating out very cheap in the few restaurants along the sea front. The apartment overlooked the harbour. We pre-rented a car at Pula airport. The roads are good but mostly single lane so will be busy in summer. we drove up through Slovenia into Italy, Trieste, and back in one day just for the crack. Lovely holiday. Around Pula are nice small towns to visit.
