Like: The staff was so kind and we got the car so soon, with just 500 KM used (that is amazing).
Dislike: I reserved a Mercedes-Benz C-Class (Premium Class), when I went to the station they told me that car is not available, but they didn't give me other cars in the same class (the same class is BMW 328 or Audi A3 ...) I got an Alfa Romeo Giulia that was so good but that was not at the same class with my reserved car.

Like: I had to cancel car hire, as my client cancelled. Avis cancelled without problems, or any charges. The staff member was helpful and understanding.
Dislike: In the beginning, he seemed a bit "under-trained", but overall helpful and efficient. So, not complaining. Thanks Avis, and hope we have better luck next net time )
