I have a short visit in Dusseldorf -only one night. I choose this hotel, because it's situation is near by the Rhein riverbank-restaurants (less that 10 min walking) and old town (15 min) and because there was free wi-fi in rooms. The hotel was the positive surprise: repared a few years ago, clean rooms, friedly staff and very good and 'many-sided' breakfast. It was really worth the price. If it's a hot weather in Dusseldorf, you must remember, that rooms are not air-conditioned. I think, that the rooms situated on backyard, are not so hot. Good hotel to stay short times, but not for you, if you are looking for luxory.
