Although the tour got off to a bit of a rocky start, since (unknown to me) they had recently changed their meeting place, the guide found me and I had a great tour (benefiting from being the only one to show up). It is a terrific way to get your bearings in Santiago and a general overview of the "downtown". The guide was very knowledgeable, able to answer all my questions and gave lots of tips on how to spend the rest of my time in Santiago. But check their website as close as possible to your planned date, in case there are any other changes (see other reviewers comments on this). Although the tour is "free", a tip is expected, but the amount is up to you. Wear your walking shoes and bring some water if it is hot.
