They are great, but unfortunately they did not pay enough attention to my need for a car parking. They gave me a partial information and so I paid a first fine of about 85 euros.
After that I got a second fine of about 75 euros and found out they gave me a parking voucher reporting wrong dates. They told me they got the fine taken away but so far they did not manage, although 2 requests from my side, to send me an email that I could forward, if needed, tho the car rental company.
So I hope I won't get a fine five time bigger than it was :-(
