As mentioned in other reviews, Paulo is perhaps the best guide we have worked with over our 20 years of annual guided tours within Europe. Our trip to Sintra was extraordinary. In addition to being an expert on the city, it's sights and history, Paulo was also extremely knowledgeable on the best times to visit and best routes to take to avoid the large crowds that visit Sintra. It was an exceptional day, again tailored to our specific interests and needs. Our subsequent trip from Sintra to and along the west coast of Portugal was stunning. Incredible views as again Paulo knew exactly the best places to visit to meet our interests. He is an exceptional guide and became a good friend during our week together. I would strongly recommend him and, in fact, we plan to visit again using his services.
