After previously renting from Sixt in Germany, I reserved a rental with them for my recent road trip through Italy. You read of bad experiences with rental companies but I never worried for a moment with Sixt. Before I arrived, I received emails confirming my reservation and the vehicle I had ordered was waiting for me when I went to pick it up. The little Fiat Panda hybrid was spotless and because there were a couple of unfamiliar design elements for a Canadian driver, the personable and patient staff member at Sixt, took me through them.
Returning the car was fast and easy. Again, the staff member was efficient and very friendly.
There were no hiccups or surprises renting from Sixt. The combination of a wide selection of vehicles and top notch staff make this a company I will turn to again when I return to Europe.
