Rental cars available at the airport. Quick turnaround in and out. Landing, 3h parking, handling + fee for 2 pax was 83 EUR in total. For longer stays there is an option to use hangar (probably no handling fee then) of local aeroclub, but I did not use it this time. It is cheaper than parking on the apron, but has to be arranged in advance - http://www.aeroklubpoprad.sk/node/453
