For a mid-range hotel in downtown Amsterdam this place is perfect. I arrived on the train from Schipol Airport and was able to walk to the Crowne Plaza from the station.
My room was smaller than I was expecting for nearly 200 Euros, but otherwise it was excellent. Everything was immaculately clean and the bathroom was very stylish with a good shower. I liked that there was an iPod dock so I could charge my phone. Internet is available in the room but I didn't use it since the fee was ridiculous. Just check your email at a cafe instead.
Overall it's a bit expensive for what you get, but the location is so convenient that I understand why so many people stay here. I'll probably be back.
