I have been renting cars for 25 years using pretty much all vendors, I am generally very satisfied with Sixt rentals, but this agency in Bordeaux is really bringing customer service to the next level, friendly and professionnal, even at peak times, they do everything they can to make your wait pleasant and your (spotless!) car pick up efficient and convenient. On some categories, they might be slighly more expensive than other rentals but this is way counterbalanced by the serenity and security of renting with them. Keep it up :-)
