We booked this hotel at short notice and gt a great deal. It is very convenient for Central station being but. Short stroll away. Other reviewers have mentioned noise from trains but we heard nothing.
The room was a reasonable size, stylish, clean and well equipped for a short stay. I particularly liked free wifi and the iMac in every room is quite cool. I used the mac to checking on lie for flights, the hotel delivered the print outs to our room, no charge for printing, excellent service.
It is a short(ish) stroll into the centre of town but you should visit the sky lounge bar first for a fabulous view of Amsterdam.
In summary a good hotel with lots to recommend it.
