I will arrive in Zagreb by train and would like to rent a car to drive to Motovun and back. Could someone suggest a rental agency that is near the train station or provides shuttle service from there? I found one at Hotel Westin, Krsnjavoga 1 (Nationalcar) that seems to be close. Europcar lists an address of PIEROTIJEVA 5, but I can't find it on the map. There are lots of rental agencies at the airport, but it seems to be a hassle to get there from the train station.
