This is a really good book! Although it might be a little bit overexaggerated or unrealistic at times, you cannot lay it back until you've finnished reading it… That's actually the biggest problem – you should bring enough time with you, i.e. más o menos two or three days… during this time you won't be able to do many other things!
The only two things I did not like:
1. The only German appearing in this book is a fat and ugly man hanging around with a prostitute… Nice image of the Germans…
2. The description of the Giralda tower in Sevilla is wrong – there are no stairs in this tower, only ramps…
However, it is really worth reading it!!
