It was convenient to pick up the car following the signs at Frankfurt T1. I switched to a VW Golf DTI which was a bit more expensive but worth it. Drove up to 200 km/h, thrilling! Returning the car was a bit tricky with the GPS, easier to follow the airport signs, T1 arrival, then follow the car rental directions.

The store service is good.

The counter staff spoke English fluently. It was very busy when we picked up the car, so we handled everything ourselves.

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 )
