It's fine.

This car rental company is great. Although the rental price is reasonable, adding insurance makes it somewhat expensive. However, the staff there are very good. Especially in Regensburg, where we returned the car! The guy there was on his first day at work, and he kindly drove us to the train station after we returned the car. If there’s a next time, I’ll definitely choose this company again.

The service was excellent and picking up the car was easy. However, the address given as Frankfurt Airport TERMINAL 1+2 was a bit vague and misleading. It actually means both Terminal 1 and Terminal 2 are possible locations. The first time I picked up the car, I assumed it was Terminal 2. As a result, I went to Terminal 2, which is quite far from Terminal 1 and required taking a shuttle train, which was very inconvenient. The other two times I picked up and returned the car at Terminal 1, which was very convenient. I recommend picking up the car at Terminal 1, handling the paperwork at parking garage 218 connected to the airport departure hall, taking the elevator down to 107 to get the car, which is in P5 parking garage.

Rented a car in Germany and Switzerland. The Enterprise rental counter at the airport was fairly easy to find. There were no lines, so the process was quick. They didn't check any translated driving license documents, just used my domestic license to get the car. However, the initial cross-border fee was high. After showing the staff the QEEQ order details, they reduced the fee by a few dozen euros (the order mentioned a capped cross-border fee). The order indicated a daily cross-border fee of 5 euros plus local tax, but the counter staff charged the maximum amount, claiming they didn't know how many days we'd be crossing the border. Is this reasonable?

The airport service was good, although it took a bit of time to find the counter.
