The rental office is next to the NH hotel front desk. The receptionist was so cute and lively, full of energy even near closing time.

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.

Enterprise is very convenient as their station is the first one right outside Terminal 2. I rented a Passat but they upgraded me to a fairly new Mercedes. Returning the car was also easy at Terminal 1, as there are service desks at both terminals. You can take the elevator to the departure level after returning the car. The only downside is that the staff speak English too quickly and keep trying to sell insurance and GPS rentals, even though the cars are usually equipped with it. Renting a car is quite necessary when traveling in Germany.
