We stayed in the apartment building of the Burns Art Hotel (round the corner from the main hotel). The main hotel is difficult to find because of the maze of one-way systems and no entry signs in Dusseldorf, likewise the apartment building is only distinguishable by the frosted glass on the door.
The room was large and clean, the decor very modern and stylish and the facilities very good, big comfy bed, decent sofa, large table, safety deposit box - absolutely cannot fault it, especially given the reasonably low price (approx. £70 per room per night).
Yes the lift only goes from 1st floor to the 3rd, but why perfectly able bodied people find that a problem is beyond me, it's one flight of stairs people! There was some noise on Saturday night from the restaurant on the ground floor, but it was barely audible from the 2nd floor and non-existent on the 3rd (I would agree that a stay on the 1st floor wouldn't have been much fun that night though).
The bathroom, although very nicely finished and well equipped was the main problem, it's tiny, the door opens inwards so you can't get in the room and the shower is over the sloped end of the bath, so you can't actually stand under it. The glass shower screen was also badly positioned and not sealed at the bottom so the floor quickly flooded. To be honest though, it wasn't that much of a problem and the quality of the rest of the room more than made up for a cramped bathroom.
You could do a lot worse at this price (and we did last time we went!), so if you can deal with a flight of stairs (!), a bit of noise and a small bathroom, this is a great place to stay.
