Biggest scam ever!!! I paid 145 euro for the Royal Palace in Madrid and the true invoice was 52.85 euro. Over the 52.85 euro entrance fee, a 35 euro fee for renting an audiophone must be added, so the total experience should have cost 87.85 euro. I am down or actually got scammed by 57.15 euro. They should be red flagged! Google should not allow them to sponsor their added and come on top of our research.
