I can only recommend this tour with Francisco. A relaxed Sunday morning cycling with a private guide through central parts of Santiago, getting to know key places without fuss nor excessive explanations. Francisco can explain the key points of modern history of Chile and relate the sites you cycle past, stopping without hurry but not too long either. The ride is not at all strenuous (I did take the cablecar up and down the hill, though) and perfect to plan visits to museums, for instances. A great guide for a fun tour.
