So we opted for a private transfer booked via Hoppa. I have used this company quite few times so I know they are reliable. The company that they have in Portugal are of a super high standard. We were greeted by a friendly young man with a clip board, who then alerted our driver that we had arrived. Our driver then turned up in a full suit and tie ! Again very friendly and helpful, greeted us with a smile and a handshake. He also took our bags, loaded and unloaded them. The car was clean and comfortable and the journey only took 30 minutes. On return to the airport the driver was already waiting for us and again smartly dressed in a full suit and tie. He was also very friendly and helpful, loading and unloading our bags.
