Sadly very disappointing! The main issue though was not the theatre or the artists, but the crowd. Oh-my-goodness: very rude tourists who were chatting during the show, laughing at the performances and just being absolutely non-caring of the others.
I've seen a couple of flamenco shows in my life and this was simply not structured well. They gave a lot of space to the guitarist who, unfortunately, was not very talented. The lady singing though and the male dancer were the highlights - both extremely good. However again, due to the crowd and the annoying sound of the air con yes, you could hear it in the background during the show, was impossible to truly enjoy the entertainment.
One of those cases where is better to spend more and see a real show.
