We have used Suntransfers for the three years,(twice per year), for our holidays in Portugal and have been totally satisfied with the service provided.The taxi has always been punctual with clean and tidy vehicles and very pleasant and helpful drivers. However, our experience in Spain in April 2016 had caused us great concern and distress, when our return taxi to the airport from our accommodation did not arrive after numerous telephone calls to ascertain the whereabouts of the vehicle, assurances from customer services, that the taxi was on its way were unfounded and it was necessary to aquire a local vehicle.Had there not been a short delay in aircraft departure times, we would have missed our flight home.Suntransfers apologised,assured us it was exceptionally rare for this to happen and offered us a discounted rate for any future bookings.Suffice to say our transport experience with Suntansfers on our latest holiday in Portugal, was excellent, although we do now ensure we have a back up!
