We stayed here as a couple in April for a few days after travelling from Bruges and the UK. Travelling by car we had everything in there form our journey from Newcastle. I booked this hotel because of the car parking as the hotels in Amsterdam did have limited parking.
Parking here is expensive so be aware. I looked before hand that there was parking at the train station with free access to a bike for a much cheaper rate, but I couldn't find it, nor did the hotel know about parking at the train station, although they did try and help.
The hotel is new, clean and efficient. It really stands up to the job. Rooms are fantastic and bathroms are amazing. Breakfast was plentiful continental and satisfying.
The hotel is situated right on the train station (trainspotters dream) while only being one stop and a few minutes away from Amsterdam central. Tickets can be purchased inside Sloterdijk train station for a couple of euros return.
Travelling back to Amsterdam if we were again soon, we would definitely stay here again.
