Ease and convenience of having a personal driver. They picked you up where you want and dropped you off where you want. We chose 4 hours but it wasn’t enough time to shop because it also included travel time to and from which was 45-1 hour. So really only 2 hours of shopping.
Great experience, the driver very helpful gave us many suggestions for our trip in Florence, beautiful Mercedes E very confortable with free water and Wi-Fi, great service!
