Thank you so much for sharing this, I am really interested in hearing stories of fellow squatters.
I actually lived in Rotterdam for 1 1/2 years, and for a short time I lived in an antikraak in the center of Rotterdam. It was a office building from the 70's, slated for demolition, and the owners let people squat in it if they paid the utilities. The building was eventually demolished and everyone was told they had to move, but it was great while it lasted. I did a lot of research about squatting in the UK, and NL, they pretty much started the whole thing off, and legalised it for a time. I hope you can help support my project, http://www.indiegogo.com/projects/a-practical-guide-to-squat..., and spread the word.
