I visited this place with my daughter before Christmas and thought it was pretty decent. For children under 4 years, it costs 1 Euro an hour. After the 3rd hour, it's free. http://www.kiiwii-ber... Another thing too, is that you are not allowed to bring food / drinks for your children in. They want you to buy from them. I did bring water for my daughter and they didn't say anything (but perhaps they didn't see it?). Just a heads-up for anyone wanting to come!
