In short, it is overcharged from false advertising, really far away to reach, and quick to see everything.

Took 1 hour to walk from Slussen Station (I did get lost a bit, but that would have only added 5-10mins). Basically, it is full of roadworks with NO SIGNS, and all the gates for shortcuts are locked by codes. After walking 1 hour in minus degrees and snowfall, we finally reached the museum. We bought tickets and the staff overcharged us by 50 each! I asked about it, and she said the price varies. However, I literally checked before heading there. After she said that, I had checked the website again, and it was still the same price! I was not offered a refund or price correction... so we went in paying 100 more for only 2 floors of exhibitions and 1 hour walk is not worth it. The exhibitions change over time, and currently, it is a "good" one. There was only 1 room I thought was nice, and another room that was interesting. I tried to go through another door, but it turned out it was the end! The entire upstairs was closed off because they held an event and did not inform customers upon arrival, or provided discount, or informed on the website, so we weren't even allowed to see the scenery, eat, or drink. There was also another room that was locked, so you can only see through the window. We spent so long getting here (even checked the directions on the website, too), but only spent about 30 minutes to see the entire place, which included reading and scanning most of the QR codes, too. I was just really disappointed, and it was just worse because they overcharged everyone and false advertisment of prices. Inside the museum, there were only about 6 people, so I don't understand why they did this. There is nice scenery outside, but you can only see it if there is no construction. This was done in both Swedish and English.
