I visited a similar museum in the Hague, so my expectations were relatively low, but I have to admit this museum pleasantly surprised me. The visit is long enough (we spent about an hour there: you might visit within 45 minutes even if you take some time thinking about the different illusions), but not too long and therefore not boring.
The illusions were quite interesting and most of them were truly worked as advertised. The staff were also extremely kind and took their time to explain to us how the illusions actually worked when we asked. They also added a few extra games towards the end, which we also enjoyed.
We also could sit on the "floor" once we finished to rest for a bit.
I understand that the price is not cheap for the general public, but we had a discount, so it was not expensive for us.
I would definitely recommend visiting the museum if you want to see something interesting and want to think about different optical illusions and test them out on your own.

Amazing place and lots of fun and illusions games. Special thanks to maryam who was very nice and helpfull and took her time to explain for us.
