Very professional

After discovering the extra charges, I went to the counter to discuss, but there was a long queue and the staff had a very indifferent attitude.

Very good

Pretty good experience. We rented the car around 7 AM with no queue. They handed us the keys and we had to find the car ourselves in the parking lot. You need to get familiar with the various controls like headlights, wipers, and audio system. Took us a while before we felt confident to drive. We booked a Benz A, but got an Opel Astra diesel version instead. The car had 6400 kilometers on it and came with adaptive headlights and a multimedia screen.

A very good car rental company. Picked up the car at Munich Airport according to the directions in the comments. The service was provided by a sweet girl dressed in traditional Bavarian attire. You need to go to the parking lot and find the car based on the parking space number. The car was very clean inside and out. The only issue was not hearing clearly about a small parking ticket needed to leave the lot, resulting in an awkward delay at the exit.
