When we booked this tour, our cruise ship was supposed to arrive at 8:00 am. Three weeks before the tour it was changed to 10:30 arrival. Called Joao, no problem. Tour changed to 11:00. Joao drove us to Sintra and gave us a personal tour of the beautiful castle and grounds. He also treated us to coffee and pastry on the way. He was very knowledgeable and spoke very good English. After the castle he dropped us off (no parking) in Sintra to explore on our own. He recommended a pastry shop to stop by. The pastry shop is the oldest in Sintra and was fabulous. Afterwards we drove to Cascais, and he showed us some sights and let us wander around the seaside town for a bit. I strongly recommend Joao if you are looking for a Sintra tour. He is kind, attentive and very knowledgeable.
