1. The store is not near the airport, located 4 kilometers away in an industrial area, in a very secluded office. See the pictures I posted. When I arrived and called, no one answered, so I had to take a taxi to the store. No one was at the store, and I had to reach out to customer service to get someone there.
2. The reserved car was not available, and they gave me an old van instead, with no Bluetooth, broken car mount, and it wouldn't start after being parked for a while. I had to turn it off and on again to get it to start. They called it an upgrade, but it was actually a downgrade, ruining my experience!
3. Hidden charges: they said there would be a 50 Euro fee for cross-country travel. The Schengen Agreement allows travel between countries, but this was not mentioned in the terms. It's really unreasonable!
4. I mentioned during rental that I wanted to return the car a day early, and they said it was fine. However, when I arranged my schedule to return, they said they were on holiday that day and I had to return the next morning at 8 AM. It's the first time I've heard of a rental company freely taking a day off with no staff, even when it's not a public holiday. They wouldn't accept the car return during their office hours. It's unbelievable!
5. When picking up the car, they said they would go to the airport, but they left me at a fork in the road. As I was not familiar with the place, and GPS was inaccurate, I had to circle around to find my way out.

In summary, after reading these 5 points, who would dare to continue renting from this company?
