I am staying in Venice for 2 days at the end of June and then will be making my way to Lovran in Istria. We will not be taking the ferry and so thought that it would be best to take the train to Trieste bus station and hire a car for the rest of the way (we fly back from Trieste Airport 2 weeks later). I am trying to decide whether to pick up the car at the airport or from Trieste city. Are there car hire places next to the bus station? Also, I would welcome any views on driving down to Lovran and whether it would be better/safer to get the bus to Opatija and hire a car from there. Any advice greatly appreciated. I am particularly wanting to make the travel easy as since I booked this my partner has injured their leg.
