Great experience with Sixt St Lucia, received a suzuki Vitara (initial booking was for a Suzuki Jimny or similar) which was not the most powerful car, granted, but was very fuel economic and brought us everywhere we wanted to go, even down the road to Anse Chastenet and Anse L'ivrogne road! The original car received developed a problem with its battery/starter but Lori from sixt immediately sorted out our issue. We reported the issue at 18 00 and they came to swap the car at our airbnb at 22 00. Lori was very communicative and gave us an eta and kept us informed throughout the process. That was the most effective communication I've ever had with a car rental. Would definitely rent again from them.
