I stayed here earlier this week for work. It was recommended it by a colleague.
NIce big rooms (well 34 was) and the breakfast was great.
Very clean, helpful staff.
Only one complaint, the wifi is not included, it's 10 Euro for the stay. It is 2012 isn't it?

I needed a place to stay in Dusseldorf on both ends of a journey as I was flying through Dusseldorf airport. It was just 21 euros to take a taxi from the airport to the hotel. The hotel was very clean and comfortable. It is also a very short walk to the old neighbourhood in Dusseldorf which is full of winding cobblestone streets and cafes. The front desk also had a convertor for my computer charger which was very helpful!

Rooms: modern, very clean (for hygienic reasons I like stone floor a lot better than carpeted floor), small, nice furniture.
Location: Between main station and city centre (5 Minutes walk from Königsallee).
Breakfast: excellent buffet in a great ambience.
Price: reasonable (especially in comparison to similar hotels in Düsseldorf center).

Rooms are small. The location is OK but not the greatest. Did not look too inspiring at night. It is two streets from Konigsalle. The bed was not very comfortable. I had a single room facing the road. I stayed one night and this was one night too much.

The shower rooms did not close. There was water all over the bathroom when I finished my shower.

And they charge 5 Euros for internet as well. Internet is fast and highly usable.
