I just got back from Qbic and I had a great time there. The hotel's super easy to find (just take a metro, tram, or train to Station Zuid -- it couldn't be easier). The room were actually very large compared to other European rooms I've stayed in, and the lobby/entrance area is awesome. My favorite part of the whole hotel were the vending machines in the lobby, which stock everything from beer to candy to toiletries. There's also a free computer to listen to in the lobby.
The only downside is the doorless bathroom. It's a little weird, but everything else was so nice that it made up for that one flaw.

First impression: To access the hotel is incredibly hard. It's hidden inside the WTC building, security checks are througout the entire building. The service is not very friendly and you have to do everything yourself (check-in and faq).
Underneath it's modern look and lavish interior decoration i's a cold, rough hotel.
The rooms: No heating, no remote controls, no doors in the bathroom, low lighting, no phones, no drinking cups, no phones (i know we already had that but it's really annoying cause there is no cell phone service either and no public phone and no wake up calls), no alarmclock,. We asked if there is a restaurant near but they said no. Turned out there was lots of places at the trainstation. Besides that we were left a message by our friends but the guy forgot our roomnumber so we didn't get it..
Besides all of the above, it's an ok hotel for a business person that travels alone and only for 1 night (the bathroom floors will stay wet after showering). If you are traveling with 2 people be aware that they can hear, smell and enjoy all the sounds while you are on the toilet.

Good luck!
btw, we did get a free glass of orange juice for all the problems mentioned above (and it was good too!)

Excellent hotel and certainly very different. Did the job very well for a two night business stop over. Also note that the hotel is a 10 minute walk across an attractive park to the RAI conference and exhibition hall.

The coolest hotel that I ever been!!
I liked it so much!! From the unusual and modern Cubi to the very nice lobby.
There is just 1 person if you need help because you don't need really help! Everything is automated and it works!
You have a Mac with free Internet access and everything is nice there.
We needed some help to download pictures to a pendrive and the people there where absolutely great and very friendly! Young people at a hotel for young people (by mind or by age)
Inside the room there are different ambiences and it's fun to use the lights!
Bathroom: ok, if you are shy, I don't recommend to use it, and for the "2nd thing" I preffer to use the lobby bathroom :)
TV cable in a flat appliance is great (I missed TV cable and flat TV in the other hotels...)
There are a bar with tall chairs very convenient for laptop or dinning there.
The hotel is located inside a business building, and there are a small bar full of people at after office.
The tram station is just at 1 block and the airport is very very close, just 15 minutes from train.
I recommended in 100%!!!
I hope to find more hotels like this and with the incredible rate of 49 euros per night!!!! Same concept than low fare airlines.
