Yago GrecoTravelerYou can not go wrong with this guide. He has the most knowledge of Portugal and you will be intrigued with his knowledge. My best vacation ever. In our walking tour we got a comprehensive overview of Lisbon—with in-depth commentary from a guide—on this half-day walking tour. Access the city’s highlights with ease, exploring the Alfama and Chiado neighborhoods and the Sé Cathedral on foot without the hassle of parking.
