Ok, let us sum up what you get from the 11\u00a3 you pay for this tour:\na tedious short walk in boring roads of the old town with loads of stops in which you have to listen to tacky stories with the guide shouting every now and then trying to scare you (if I lived in the old town I'd report this to the police), then you enter in the so called vaults, and what you get to see are:\n\n1) A narrow and rotting staircase\n2) Two cellar rooms with a bumpy floor\n2) a corridor\n3) a narrow cellar room in which you are told about a lady on a tour who heard whispers coming from the backwall.\n\nNot much indeed. The time is filled up by the awkwardly tacky story-telling\n\nThe underground rooms are but a cellar. I am from Italy and most italian buildings have cellars which look complitely identical, with the sole exception of salami and wine which here were absent.\nThey spend some time telling you that people used to spend time there and that they found oyster shells which might indicate that the room was a tavern of some sort, but the whole thing is rather pathetic. 3 minutes would be too much to take a look at what is there to see. \nThey show many stories underground in boards and posters giving the impression that you actually get to explore a complex system of underground tunnels and rooms, but then you only get to see three rooms and a corridor.\nObviously we complained and the manager was hiding behind the good reviews. Oh dear, a bunch of hyped-up tourists giving 5 stars to everything they've done is hardly an excuse to rip people off in this way.\n\u00a32.50 would be an adequate price, and without the time-filler, I mean the tacky storytelling.\nStrongly advise you not to go on ANY tour of this kind.
