After reading past reviews, I approached our Sixt car rental in Martinique with concern but it was a flawless experience. The airport shuttle arrived within 10 minutes and took us to a clean and modern facility where cheerful, smiling staff processed our rental in 5 minutes. When I asked about a cleaning fee, the young lady assured me that this wouldn't be charged and it wasn't. And they gave me a brand new Dacia Duster which is the vehicle I'd reserved. Based on my experience, I highly recommend Sixt Car Rental at the Martinique airport.
