They charged a 1400 CZK parking fee at pick-up, starting from three days before the pick-up date. Now, the rental company doesn’t acknowledge this fee, claiming there was a free parking card in the car. First, the staff never mentioned this when we picked up the car; second, there was only a paid parking card in the car.

Fine, nothing exceptional.

It's quite normal, nothing special.

I rented a GPS from the store for 8 euros per day, but it had no signal when turned on. The reception said it would work outdoors without issue. However, it didn't work outdoors either. I drove a bit but still no signal, so I had to go back to exchange it. Everything else was fine.

Front passenger side window went down by not back up. All other windows were fine so likely a broken window motor. The car only had 15k kms on it though. Called the Budget support line but got no real help. When returning the car, mentioned it to the guy at the desk was not at all interested and he literally said "what do you expect me do to about it".
