After our first experience in Barcelona we've come to look for these tours in any city we visit, and never been disappointed. Jef was no exception, and we now focus on small group tours like this because of the storytelling. Each guide does their own research so although what you see is similar, how you see it is quite different with each one - beacuse each guide has their own interests. That means that every time you look at a city, you see it with new eyes. We appreciated ending up at a nice place for a drink at the end - and even more that Jef took the time for a chat, maybe collecting more stories. He didn't have to do that, and that is what made this tour special.
