We booked a private ride on Positano shuttle twice - one from Naples train station to our Positano hotel, and then again from our Sorrento hotel to the Naples airport. They were reliable, responsive, and showed up as requested in decent vehicles. Note that if you are 3 people with 3 "large" bags (larger than carry-on) you need to book a van, rather than a car.
Our driver on the way to Positano was a bit grumpy, spoke very little English, and was a pretty aggressive "road rage" type driver, tail-gaiting, driving fast on the narrow windy mountain roads, and cussing out drivers along the way. But we ended up arriving safely to our destination. He may or may not have slightly side-swiped a car exiting the Naples train station.
The driver from Sorrento to Naples was much more calm, which was nice, especially since it was just 4 am, and didn't need any near-death experiences. Overall, giving them a 4 for communication and reliability, but maybe they should request input on drivers after service to get customer input! read more
