Very convenient.

Overall service was okay, but there was a tire burst and had to exchange the car. The roadside assistance was very slow, and a model worth thousands was taken by the staff from the car. It wasn't placed in lost and found even though it was just a few hours. Sigh.

Due to flight issues, I didn't arrive on time and the reserved car was no longer available. I had to switch to a compact model or pay extra.

Convenient and fast

I booked an Audi A4 wagon, but they gave me a Mercedes E220 wagon instead. Very satisfied! Picking up the car was just a matter of completing the paperwork at the counter and following the staff's instructions to get the car myself. Returning the car was even simpler: I handed over the keys at the counter, was asked if the tank was full, and was told everything was fine without them even checking the car. I picked up the car 2 hours early and returned it 1 hour late. No problem. Germans are so trusting and accommodating. Highly commendable!
