Outstanding! Excellent info provided. Antonia (I think that was her name), made the tour an easy path to understand the history of Catalonia, Spain. Without any doubts, I will take it again.
If you are interested in gothic architecture this tour is worth doing. The guide was knowledgeable but most of the information as given in Spanish with only snippets in English. As this as advertised as an English speaking tour we were the only English speakers we were disappointed to have missed most of the commentary.
The tour was interesting, but a bit too long, mainly due to the fact that there were actually two groups - English and Spanish - combined in one, so the guide repeated everything in two languages.
