I had a very good experience with Sixt, I rented an automatic vehicle for seven days with them on Martinique. The car was as advertised, my French is so so at best, and the gentleman who helped us initially spoke good enough English to get us going and on our way from the airport. I misunderstood about where to return the car on our way out, and dropped it back off at the airport, with not a lot of time to spare before our flight. The lady at the desk let us know about dropping off at the wrong location, and when I told her about the time crunch, she called the shuttle driver to meet us at the airport, and then we could follow him to the off site location to drop off the car and he would immediately take us back to the airport. Great customer service and would rent from them again if I am ever in the area again.
