Where to stay in Amsterdam?

This is for those of you who have been to the dam before.

Here's the deal, I'll be flying out Amsterdam after around 7 weeks of volunteer work in Europe. That gives me around 5 nights in and around A-dam. Now, I've been there once before for last years Cannabis Cup. I know where to smoke. What I don't know is where should I stay?

Does anyone have a favorite place or at least something they could recommend? Let me know, I probably need to book something in the near future.

What level of amenities are you looking for?
Do you have a location preference?
