The museum is subpar to an extent, that calling it a museum is not accurate. It's very small, there are a few interesting optical effects demonstrated on the walls, but roughly half of the exhibits on the 2 floors are dedicated to photo opportunities for IG, not actually anything worthwhile to see. The price is ridiculously high (18 EUR) for something that didn't even last 30 minutes, when we even stood around and talked, solved a puzzle (by the way not an illusion) and waited to enter a few of the exhibits. It wasn't very well kept either (broken mirrors at places, dusty)

It was full of children (mid-day on a Monday), so I assume the marketing is towards them and tourists who don't know any better, but to me the entire establishment is just a cash grab, as even if it was aimed at children, they don't warn you of this, nor is there anything for the kids to actually do for more than 30-45 minutes.

The two most interesting exhibits are the small room with mirrors, where you can see yourself from different angles and with reversed image and the short disorienting tunnel on the first floor.
