Alissa gave exceptional service to say the least. The option to upgrade at a fair price to a vehicle that would better suit our travel needs was presented but was not pushed their value in additional coverage on the car is unlike any other options I’ve been presented by other brands at a rate that could not be beaten. cars are always clean, smell good and drive without problem everytime. I will only use sixt rental car when I travel thanks Sixt and thanks Alissa for the outstanding service!
