We travel as a family often and over quite a few years now we have used Sun Transfers for our airport pickup and return transfers. So far our experiences have been very good and we have found them reliable. The only exception to the rule was unfortunately in Dublin where we had lengthy waiting periods on several occasions for the driver to show up. Also in Dublin we were given a grubby taxi or cheap alternative instead of the booked/paid for luxury van a couple of times which was annoying. All over Europe apart from Dublin we wouldn't hesitate to use Sun Transfers.
