We all enjoyed so much this tour. We saw planty of different places that we wouldn't have seen if it wasn't for the excursion.
Our guide, Dominic, did a excelent job combining historical sites explenations with really good route directions. Also he tried his best speaking in Spanish, and we completely understand him.
We are definitely recommending this tour to everyone that is willing to do some sport while seeing the city. It's fun and you can see a lot in just three hours.
