The insurance details were not accurately described; it didn't cover everything as claimed. We ended up paying an additional 500 euros at the counter.

The rental and drop-off locations were too far apart. I had to inspect the car myself after getting the keys and ran back and forth with my suitcase three times. What should have taken ten minutes ended up taking an hour, and I was drenched in sweat.

The Hertz rental counter at Frankfurt Airport is very prominent, and the staff are enthusiastic. They held the Bus for us even though our flight was delayed. The procedures are simple.

There is a wide range of vehicles to choose from, the location of the car lot is convenient, the cars are new, and the process is fast and simple. However, be cautious as they may claim that the car you originally booked is unavailable and try to upsell you to a more expensive, luxurious model, along with unnecessary insurance and equipment. The additional insurance and equipment they offer are quite pricey. In my opinion, roads in Europe are generally good, and drivers tend to follow the rules; if you have good driving skills and are cautious, the basic insurance is usually sufficient. Dare to say 'no' to their 'enthusiasm'.

Was offered an option to upgrade to SUV (Ford KUGA 2.0) by paying EUR5 per day. Happy with the upgrade!
