Very kind and speedy! Exceptional! among the rental car services in Lisbon. Having used many car rental services in Lisbon over the years, Sixt is by far the best. They provide accurate service package explanations, no unnecessary upselling, and I was able to get the same class of car I booked for the first time. The car was also very clean. In particular, the staff member George impressed me with his kindness, accuracy, and quick service.
