Czech - Austria - Germany

My first experience was average: 1. We booked a 7-seater automatic, but were given a 5-seater. Although they explained that the 5-seater was in better condition and more expensive, the rental agency simply didn't have a 7-seater automatic. 2. There were very few staff members. After renting the car, there was no one to guide us to it, and it was not where they said it would be. We searched for ages across three levels. It felt unorganized. 3. After finding the car, there was still luggage from the previous renter inside. 4. The staff were very impatient when explaining things, eventually ignoring us completely. 5. At the rental, we were told to use 95-octane gasoline, but luckily we checked and realized the car required diesel (thankfully we asked multiple times). It was nerve-wracking initially, worrying if we were wrong. 6. The return process was relatively convenient; filling up the tank was straightforward with no extra hassle.
