This walking tour is exceptional. Javier is very well informed, clear and mindful. And very entertaining and quick witted at the same time. It can get warm and trying under the sun and he gathered us in shady spots while describing the places of interest. He also selected spots where folks who can get tired while walking can sit a while - something that my wife who was a little worried about the long walk really welcomed. These are "free tours" without any public funding that I know of, in that there is no upfront or fixed fee. At the end of the two hour tour you can give whatever you like, or even nothing at all. We gave ten Euros each and our local relatives subsequently told us that was about typical. We'd have been happy to pay more and got a lot more than our money's worth. read more
