It is easy and lot of option can be chosen.

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.

Picked up and returned the car at Prague Airport, the staff at the store were quite friendly

The counter staff at the budget was not pleasant not smiling , it seemed like we were bothering him! very unpleasant!

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.
