1. Due to a train delay, I called the rental company in advance to confirm a 10-minute delay, expecting to pick up the car by 19:10. I arrived at the shop at 19:07, but the staff had already left, so I could only pick up the car the next day. 2. I booked a premium wagon, but was given a sedan instead.

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.

There was only one person on duty, waited for half an hour. The parking spot number for pickup was incorrect, and there was no one around to ask. No one to explain the car features.

They didn't notify me in advance that the reserved model was not available, which is not user-friendly.

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!
