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.
