We arrived in Lisbon on a national holiday so, with vehicular traffic limited, Silvia suggested a walking tour. It was the perfect introduction to this beautiful and vibrant city. Silvia was knowledgeable, pleasant, and very flexible to our preferences. She was also wonderfully patient when we discovered a shop we found difficult to leave. We recommend this tour for those with limited time or for anyone wishing only to get a taste of Lisbon, And we recommend Silvia as a 5-star guide.
