I've rented a Kia Sportage with Sixt before and the whole process was simple, friendly, and cost-effective. Sixt has better deals if you are crossing the border down South, as well. I was so pleased they decided to open a branch in the city-centre. Billy and James at this office were very helpful for my booking and kindly explained everything clearly. They provided excellent service and I'd be happy to work with them again. Thanks so much!
