Sara was a wonderful tour guide for our Douro Valley day trip. We were blown away by our stop at the first winery, and equally impressed with our lunch option. The afternoon winery was also just so scenic and Sara did a great job keeping us on schedule so we did not miss any of the events. She was also very entertaining and knowledgeable across so many different subjects. Sara was kind enough to make us dinner reservations for that evening, and also gave us numerous tips about how to spend the rest of our time in Porto. Everything was just as we expected and more, as she went above and beyond on this tour. We would absolutely contact Sara again for our next trip back to Porto!
