Stayed here for 4 nights with my girlfriend during October and absolutely loved it. We stayed in a queen room on the 11th floor which was fantastic, the room was more than adequate and was furnished very well including a nice big flat panel TV. Staff were helpful when we required a travel power adaptor and the check-in/check-out process was as painless as it can be.
This is genuinely a great location for anyone looking to stay in Amsterdam Central. I spent a long time looking for a suitable hotel and after reading many reviews on here I got completely confused about its location and how long it would actually take to walk from the hotel to the 'local amenities' as there were no tram stops nearby. I can happily confirm that it is a solid 10 minute walk, and a nice walk at that.
I would definitely stay again
