Really convenient location unless you absolutely need to be right in the center of everything. The hotel is a 200m walk to the closest underground station (Isolatorweg) which was very convenient, but it was about a 30 minute commute into the city center. Very easy train ride with just one change (Zuid). The hotel parking was full when I got there which I sort of thought they'd have enough for the guests, but you can park in the front for 15 euros a day and free on weekends.
As for the room, it was very comfortable and I slept quite well during my stay. My only issue is that there isn't any instant coffee or tea, forcing you to go to the cafe downstairs (or the conveniently placed BK next door). The linens aren't the softest, but the bed was very comfortable. If you want to stay in Amsterdam and be away from the crowds, look no further.
