This is a great hotel to stay in. Easy to use and check in large and funky rooms all very well maintained and different. And given the easy access into Amsterdam worth staying in even if you are visiting the city. BUT the restaurant/canteen is very expensive indeed. Food quality good but if you want value for money bring in your own food - its even cheaper in the airport itself. That would be my only gripe. Everything else was spot on.

Sit on the loo, close your cylindical capsule, preselect the LED mode with your personal wireless control pad & you will be teleported to a differerent dimension in time.
Well may be not that good; but innovative user friendy technology is used in all aspects of running this hotel.
Whist budget for the area, with reasonably compact rooms this hotel has a huge 'wow' factor. Beds are comfy too !

Perfect for a stopover for singles or close couples next to Schiphol airport. Though it is not directly connected to the terminal and you have to walk about five minutes through very recent construction adjacent to the terminal building - the hotel is worth finding your way there.
The elevated bed takes about a third of the room, the round bathroom fixtures another third. Rooms have no carpet, no minibar, no coffee makers, no closets, no phones and no decent desk - but some space age mood lights and one master remote control for TV, blinds, the mood lights, and the aircon. The lobby area features mid century design furniture classics, slightly overpriced but healthy sandwiches and salads, a couple of weird self service terminals for guests - and some eager young staff helping you along. Geeky? Yes, to the max - but also very comfortable, quiet, clean, and ultimately very relaxing.

I stayed at the CitizenM during a trade fair. At such times it is very difficult to find a room at any kind of decent price in Amsterdam, so being able to book the CitizenM for a reasonable rate was a bonus. There was no apprehension about the cleanliness, as the hotel is brand new.
Check in was on a computer at the entrance. There was a member of staff there to help with potential problems. The room was pretty small and played on its techno, wiz-bang modern theme. There is a pod for the shower and one for the toilet in the middle of the room (other peoples' photos show these). This means that there is not much privacy whilst 'visiting' either pod.
Room facilities like lights, TV, blinds are controlled by a central touchpad. I guess this is fine if it works, but ours didn't, so for a time it was not possible to change channels on the TV or to switch the lights off. Mounted on the wall, the touch pad glowed brightly even when all lights were off, which - in a small room - could disturb you whilst trying to get to sleep.
The staff there were very friendly and helpful.
Again the hotel let itself down technically by the fact that my room key stopped functioning at the till, so everything had to be paid cash.
There was no breakfast included, so everything had to be bought - that was pretty pricey. If you had time, it may be better to nip into the airport for some breakfast.
All in all I thought the hotel was trying to play on its technno image too much. There's no point being ultra modern if things don't work and you have to go back to the old way of doing things anyway. It just seemed more wiz-bang than practical.
I would stay there again in the same circumstances, but would probably try to find something in the centre thats a bit more classical....
