Jana is a delightful guide that made Gaudi's (or actually the whole modernisme movement's) vision truly understandable. She surprised us with a lot of little quirky stories that are not even known by the "pro" guides e.g. at Casa Mila. Consequently, we can only recommend her and the tour to everyone planning a trip to Barcelona.
Shanin came to my Gaudi excursion with a friend and they were both very pleasant, highly educated and courteous people who were genuinely interested in learning more about our most architect and about Modernism in general. I greatly enjoyed showing them around and hope to see them back in Barcelona some time in the future.
