We did the Parc Güell live tour with Ariadna. She was great and took us through the wonderful world of Gaudí during a walk over the most beautiful park in Barcelona. She told us every detail and interesting information about the beginning and development of Gaudí's protect. It was curious to see someone walking and showing us a place that everyone should visit al least one time in life. I recommend this tour to everybody!! Fantastic Ariadna, thanks a lot!!! We'll meet again soon
