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.
