The price was fantastic, and the car was great. I was given a free upgrade without asking. All very nice. It took a long time to check-in. I decided to return the car the night before it was due. Although the door to the office was open, and three customer service representatives were present, I was told that they were closed, that I could not leave the car in their lot, and that I should park overnight in the adjacent underground public parking lot. This morning, I returned and had to pay for overnight parking in the public lot. No one at Sixt was sympathetic, repeating that they were closed last night. I questioned why I couldn't have left the car there with their other cars. They only repeated that they had been closed then. I think they could have offered to reimburse me for the overnight parking.

Was quoted under $9/day and ended paying over $1100 for 3 days

Agents were friendly and helpful both on the phone for the reservation and in person for the pick-up. Vehicle was in great condition and perfect for our needs on the trip.

Staff seemed disinterested. Location was not air conditioned. No instructions on how to operate the car. Car was dirty

Terrible experience so far. Charged twice for the rental, both amounts more than the quote in the booking. $1200 deposit put on hold on my debit card which took many days after the rental to clear. Booked a Ford Focus or similar but was given a Ford Transit Van as the only car available and told this was a free upgrade, but I had booked the smaller car for a reason because I would be driving in narrow streets. Official drop off time was a day later than what I had booked. Staff at the drop off hardly communicated at all. Only asked for the keys, then told me the amount and had me sign in as few words as possible. Left me standing for a long time without saying anything.
