It's right next to the train station. I didn't hear any trains at all through the windows. Trains to the airport leave every 15-20 minutes, and Amsterdam Centraal is one stop down as well. It's close enough to the city, but far enough for some quiet time when you want it. The location is a bit outside of the heart of Amsterdam, but that can be good if you're tired of all the sound and lights.
Location was very good, very good trains connection to City Centre. Brekfast should be more rich.
