We waited an hour to get our car, they did a free upgrade for us which were nice. After reading the comments, I bought the full insurance 37 euro per day so I don't need to deal with all the charge after (especially when they gave us a mercedes). Will wait for final bill (2 weeks from now) and complete my review after!
