We booked a tour of Sintra, Pena Palace and the Golden Triangle through Sintra Magik. They were very accommodating of our scheduling needs. Diogo Costa was our private tour guide, and we found him to be awesome! He arrived at our hotel promptly at the scheduled time and had bottled water in his car for us through the day. He is a native of the Sintra area and intimately knowledgable of the entire area. Diogo has a very relaxed, congenial manner which made it easy and comfortable to spend the day with him. The pace of the trip was perfect and our guide was always considerate about having us see and do what we wanted. Diogo also arranged for us to have lunch at a wonderful place in Sintra. He called ahead so that the food would be ready and therefore optimize our sightseeing time. While he is Portuguese, his English language skills are impeccable. I would give Diogo Costa and Sintra Magik Tours my highest recommendation if you’re looking for a private tour.
