The location is fairly easy to find. If you come out of T1 at Prague Airport, it's the building directly opposite the main entrance. I booked a Golf but got a Yeti instead. The car was very new and overall pretty good. Due to driving to Austria and Hungary, they charged me a 42-euro border-crossing fee. This fee is my only concern as my friends who have previously driven in Europe never mentioned such a charge. I'm also wondering if this fee would apply if you didn't indicate your intention to drive to other countries when renting the car.
