Sandra, was a great guide. She was on time, friendly and knowledgeable about our tour. When we ran late (our fault) Sandra was able to change the tour and organise taxi to take us to our next stop to make up time. Sandra made our time in Barcelona really interesting as she told us places to eat, and visit as well. Sandra spoke English well and we were all able to understand what was happening and why. We will be recommending Sandra and Tours by Locals to friends and relatives when they travel.
