He was very knowledgeable about the regions we passed through and happy to answer our questions. The restaurants he picked were delicious, ones that we would not have known to stop at!
He also passed along a lot of general advice, even helping us with recommendations for which things to do during the days outside of our trip with him.
Overall we had a great experience and found Antonio to be super kind and to genuinely care that we got to experience the best of Portugal!
