'Appalling service'. Totally unreliable and unhelpful. I pre-booked the transfer several weeks before flying; a 5.30am transfer from Seville centre to the airport. 24 hours prior to the pick-up I received a text message confirming details. On the day the driver failed to appear so the 'emergency' number after 5 minutes, as advised. The contact centre rep put me on hold for several minutes before returning to advise me that no one would be coming due to "logistics" problems, instructing that a refund would be given along with apologies. I pre-booked because we had an apartment without a reception and and early start. An apology and a refund is not much use when you need to catch a flight. They contact centre rep could not, or would not, call an an alternative on our behalf. More apologies but no action. In summary we were left to wander about at 5.45am in the morning in the hope that a taxi would pass by. As it happens we got lucky, I spotted an empty one at a taxi rank close to a tourist spot and we still made the flight. Nonetheless, I have totally lost any confidence in this operator. They are not there to help when you most need them. In their own words an 'appalling service'.
