If travelling to Portugal excellent book to get you going. However do your own research. For instance beautiful Pineche near Obidos is not covered. There is a bias towards Lisbon and Algarve however Porto and Duoro Valley which is covered is a must see.
Well this book was about ok. Everything fell together towards the end of the book. Even though there was nothing grammatically or otherwise wrong with the book I think it is the subject and how it was treated which at least to me was not engaging. However if you are into automaton, clocks etc you may like it.
