We went on a private tour to Sintra from our hotel in Lisbon on 1st Sep 2019. We are very thankful to our tour guide Joe as well as Corpo Santo Hotel for an excellent half day tour to Sintra Mountains tailored to our request. Joe was very knowledgable and was receptive to our needs. He was very friendly and professional. We were able to make several stops at places of our interest and snap pictures. Although the tour was meant to be 4 hours we went over by at least another half and hour. Joe did not rush us. It was quite a different experience to going in a tour bus with lot of other people. If you want mind spending a little extra money for a life time experience in Sintra mountains, then I very much recommend this tour operator for you.
