English communication was very smooth.

When we arrived at the rental location, we were told there were no automatic cars available and were directed to rent on-site from another car company. After extensive negotiations, we were instructed to go to the airport to pick up the car ourselves. Upon arrival, we were further delayed and charged an extra 69 euros for airport parking. Overall, the service was inefficient, the staff were rude, and the experience was unreliable.

The service and the condition of the car were both excellent.

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.

I was supposed to pay 332 euros at the store, but I ended up paying 772 euros. They said they would explain it to me on the same day but never sent an email! The bank has already deducted the money and Hertz still hasn't responded.
