Rely on GPS, European cars are very fast

Very good, the staff at the rental company were very friendly. I had never driven a car that required pressing the brake to start the engine, so I struggled for a bit. In the end, I had to call the staff up to the parking lot to help me.

Had to return the car early due to a family matter, but the additional rental fee, cross-border service fee, and insurance were not refunded at all.

Fine, nothing exceptional.

Picked up the car at Prague Airport. The store is not far from the arrival hall, just a few minutes' walk.

Like: I liked that it was possible to get a great last minute deal within my budget. The reservation desk guy was helpful and friendly. We got the car as scheduled with no delays or waiting.
Dislike: We booked VW golf class and got a Seat (not sure which make). It was kind of a nice upgrade. However, this car has very uncomfortable front seats. It has nothing to do with Budget, just a thing to keep in mind.
