There were issues with coordination.

During return, the staff mentioned that the interior was not clean and there was sand. They asked for a 15 Euro cleaning fee or instructed us to go to a gas station to clean it before returning. There was no prior notice about this before renting, which felt quite unfair. Especially if you're rushing for a flight, you definitely can’t avoid the cleaning fee. Poor experience with this aspect of returning the car.

Long waiting time aside, they insisted on giving me an upgrade saying my two suitcases wouldn’t fit in the Fiat 500 I originally booked. They wouldn’t even let me check the car. Instead, they forced the upgrade and charged me an extra 25 Euros per day, claiming it was a good discount, which doubled my original cost. I had to accept it because I was in a hurry. I chose to return the car in downtown Paris. The train station is in an underground parking garage, but this was not mentioned on the document. I ended up driving around Paris streets several times.

Arrived at the counter around 6 AM to handle the paperwork and pick up the car. It was in Terminal 2, very easy to find. The staff at the counter were very friendly and quickly completed the procedures. Got the car right outside.

There is no way to communicate with them France Hertz because some problem in their call routing process. Informed India Hertz and US Hertz too. But they could not help. Also road side assistance there is no response in France
