I will have a day free in Istanbul as part of connection. I have often used the Hop on Hop off buses in many cities and find them to have some gems of information that I would generally have missed. I have been to Istanbul on several occasions, but this time would like to chill, and use this service.
However, when looking at prices, my jaw hit the ground - I saw a price of Euro 125 for a one day pass!!

Just to put it into perspective here are some comparisons, all in Euros;
NYC 44
London 29
Barcelona 25
Paris 28
Am I looking in the right place, or is that the actual price?
