Quite satisfied

The staff were extremely rude and ignored customer requests. They downgraded my reserved Mercedes E-Class to a small Toyota without permission. The staff also did not inform me that driving in central London requires a congestion fee.

Okay

The staff was alright; it was early in the morning so there weren't many people. I rented an Audi A4 wagon, but they gave me a Passat wagon, which runs on diesel. They claimed it came with a built-in navigation system, so no additional GPS was needed. I didn't bother to argue. Later, I realized diesel is more expensive than petrol in Europe...

Forced to buy insurance to change the car model
