The guide assigned to us only served to avoid the queue at the entrance, after which he literally abandoned us, inviting us to tour the imposing building on our own. It should be underlined that the language spoken by the guide was only English, although other languages were guaranteed (French, Spanish, German). Obviously it is reprehensible that the Italian language is not included, considering that there are many Italians. The electronic apparatus provided for the possible translation turned out to be just a gadget to justify queue jumping. Overall, modest overall rating.

The tour guide was very nice and helpful. He explained everything well too. Did you really need one? I don't believe. You can read what you need to know in travel guides and what you have seen you have done on your own - without a tour guide. If you're unsure, this is definitely a good idea; My experience in Istanbul is that you don't have to book tickets with a tour guide for many things

Basically a very good idea. We just neglected to download the actual audio files in the app beforehand, but that wasn't the guide's fault. The guide accompanies you into the storage area and gives you lots of interesting information... recommended
