English communication was very smooth.

They could not provide the vehicle as per the contract and transferred us to AVIS, promising to refund any extra costs. In reality, we incurred significant losses and the other party did not offer any compensation.

Not very attentive to Chinese customers!

The car provided by the company initially had no trunk space, but we had booked a car with a large trunk. We coordinated with AVIS to get a replacement. The car was very dirty when we first received it. After requesting a clean-up, it was much better. Overall, the experience was quite convenient.

We indeed got a Mercedes ML250. We chose the rental and return location at Frankfurt Central Station. The rental office is inside the train station. We met a kind German who accompanied us all the way to the office. The car is in the underground parking garage P3 of the train station, and the pick-up and drop-off are at the same place. We were worried about additional fees, but today we received the charge notification, which matches the order amount, so we are relieved. It's worth noting that the rental office doesn't inspect the car with you in person, so we were worried something might come up after returning home. Fortunately, all was well.
