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.

The car rental company is very professional but there is room for improvement in efficiency.

Fine, nothing exceptional.

Although the store opens at 8 AM, the staff started working at 7:30 AM. The pickup and drop-off processes were very fast.

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.
