I was on a business trip for 8 days in Amsterdam. The hotel is modern but not enough for 4 stars. I also booked it very late and the prices were really high. It was ok, I was satisfied because it was close to my work but for 4 stars hotel could have been better. Also, some slippers and more light would be better.
There is a fridge in the room which is important if you want to save on food a bit.
