Very unpleasant staff! We went as a group of 10 adults and we were followed by a lady from the security, who was picking on absolutely everything: we were looking at the wrong way and standing in the wrong place, we were asked to move, while in the same aisle there was a huge group with a guide. And so the whole tour we were harassed, criticised and pressed. We were covered, did not break the rules, behaved culturally and talked quietly. In the end, the lady called the head of security, and then we couldn't stand it and got indignant. The lady was never able to explain what rules we had broken and what she didn't like. After paying 25 euros we were subjected to reprisals. This is not hospitable and absolutely inappropriate! Shame on you, security staff. Don't overstep your authority by hating people based on nationality or religion.
