I can't recommend Bravo Bikes and Kaspar in particular highly enough. As a tour operator myself, I know the importance of a friendly, personable touch, and Bravo scored 10 out of 10 for this. Despite being the only client on a November day, Kaspar was delighted to show me all the highlights of Madrid, and so much more. It's fantastic to speak with a local, to understand the real Madrid, its people and politics, and Kaspar gave a real interesting insight into these, as well as being very knowledgeable on his city. He does not have a script that he keeps to rigorously - he answered all of my curious questions about things other than the history of Madrid, from the economy to where I could get a good value meal and a flamenco experience. Such a wonderful command of English, too. A first rate service, and a wonderful way to take in all there is to see in the city.
