Two of us stayed here for four nights to visit the Dutch GP. Excellent location, right in the tourist area of Amsterdam and the hotel straddles the railway station which provides train services to Zandvoort racetrack.
The room was basic with wifi, tv and room safe. The safe was unusable as it had been left locked by the previous user.
No extra pillows in the room, these were available if you asked at reception. We saw many people doing exactly this.
No tea/coffee facilities in room.
The bar/restaurant was excellent, good food (limited options) and the bar staff were friendly and helpful.
Reception staff get a mixed review from us. Some could not be more helpful while one guy was particularly rude as though he didn't want to be interrupted when I advised him that the coffee machine in reception was out of milk.
Overall, location wins the day.
If you are just looking for a base to head out from then this hotel ticks the boxes.
As a final note, the hotel is cashless, as is much of Amsterdam that we saw.
Don't bother bringing Euros with you.....You can't give them away.
