I toured Sagrada Familia in Barcelona via if Viator. The tour provider, Amigo Tours was poorly organized, difficult to understand and follow through the crowd. The tour was conducted in English and Spanish by a Russian tour guide. She appeared a bit sloppy and raised a tacky umbrella for us to follow her. When she spoke in English she appeared knowledgeable but lost some of the group as she moved through the crowd. I heard some of what she said but had to focus to understand. There was no enthusiasm and I felt the 109.00 euros was far too much for what was delivered. I will not likely book through Viator again because it is apparent that vetting providers is a bit inadequate.
