Location for pick up in Bucharest Central Car was clean, but do read the comments.
Casual attitude of the staff for scratches/damages when receiving the car from Sixt, not the same while returning to airport, Note to other users, please make sure that you check the car carefully, not just indication on paper on the car image for damages, but also what's written on the paper about the state of the car, we almost got caught as there was damage on the car not indicated on paper, but were told 'It is a problem' while returning. It needed a wait of 30 min for someone else to hear the same story and state 'car was ok'.
