Very disappointing. Reserved a car, but upon arrival, they said there were no cars available and couldn't tell us how long the wait would be. We had to pay extra to get a different car, and the only option was an Audi A7. Without informing us of the price, they charged an additional 1,400 euros to my card. Up till now, I have no idea what this charge is for.

Sometimes the queue at the counter is very long, sometimes it's completely empty. It depends on the time; on average, the wait is 10 to 20 minutes. The service attitude is alright; some are very business-like, and some are more eager to help. Encountering a good employee is a matter of luck.

The price at the counter was different from the price online. Not sure why. It's unreliable, no additional services, just a price difference.

The deposit was withheld without explanation. I only realized it several hours later when I received a text message. When I asked about it while returning the car, they finally provided an explanation. The wait time was very long, it seems their business is too good.

The store at Frankfurt T2 is very convenient, located just to the left of the exit.
