If I tried to convey my feelings in brief it would be OMG! This centre is full of different video installations which fans of modern art and technology will enjoy, and you can wander there like in a maze. At the same time, I feel that some kind of a map would be helpful. It's nice that you can explore the area as you wish but when you want to get somewhere specific, it's hard or sometimes impossible.
I would recommend avoiding weekends and holidays because it gets crowded, on Saturday afternoon all tickets were sold out and one room had a queue with more than half an hour waiting. At least 2 hours would be necessary to enjoy everything the centre has to offer. Most rooms are pretty dark and some rooms are stuffy so be careful.
