I have taken over 20 tours by local and this is first time I am giving a review like this. I feel compelled. Alvaro is passionate and has expertise and for that I give him five stars. He accommodated my wife's mobility issues the best he could. This brings me to bad point. When we got o Mosque he said he had the tickets and that his friend would have to be our guide in the mosque in Cordoba. Nothing was mentioned about additional costs for his friend prior to the actual trip and not even on the way there. It was a sudden announcement and description says guide services are included. Even at mosque he did not say there would be costs for his friend.At very end, when we arrived at our hotel, he said tickets were not included, which I knew and then after giving me cost he added that neither were services for his friend and said there would be extra 74 euro charge. I knew the ticket price for seniors was 12 euros each, which means he added 50 Euros for his friend's services. As explained, this was never mentioned before the drop off and should have been included in trip details or at least clarified prior to booking or at least from the start. It was not. My experience has been guides have told us to buy tickets. Even when he mentioned he bought tickets and his friend would guide us nothing was mentioned regarding extra fee and I assumed he was taking care of costs since he could not provide services. Rather than argue I simply paid and it was lucky I had 75 euros in cash on me. I say this so next person who books will not be surprised and he should change his detail page. The point is not the cost but manner in which it was handled, which left bad taste. I should mention his friend was excellent and probably would not have objected if told up front and 75 is in normal range for hour in mosque
