I'm currently not living in Amsterdam but I still visit friends quit often, especially for the good parties.
Working wise you might want to look up "Anti Kraak" or ask around. For young startups it's the best way to score a nice place to work in.
A friend of mine managed to get a old-church in south-amsterdam for his paintings, and I worked in an abandon school building with all kinds of different start-ups. (70 EUR per month and the place was huge)
Downside for you is probably the language barrier to get these sort of "buildings" and I can't find a website in english for this, but you can always ring them and ask.
Here are a few numbers/pages:

Plus side of this are the locations and buildings you could possibly get. Big spaces and top locations.
Down side is that you might not find the social interaction you would get with co-locations unless you find a building that is used for several other startups as well.
Will ask around and see if I can get a direct phone number with someone that can actually tell you right away if something is available or not.
Enjoy Amsterdam and I'm always up for a beer or 20+.
