As we were attending a big exhibition in Dusseldorf, we had left it last minute to book a hotel in the general area.
Finding somewhere was more important than price, and we found the Mirage with rooms available.
It is a large hotel at 7 stories but has a busy station to one side and a busy high street with trams to the other.
There is no airconditioning so if it is hot, with windows open, you will require ear plugs.
The establishment is 1980s and now rather tired although comfortable enough.
The staff were courtious and helpful and a surprisingly good breakfast buffet was provided.
We would rate this hotel as an up to €60 a night establishment, but watch out because during large exhibitions they can charge an eye watering €190 a night.

We book double room.

When we get into hotel, there was no avaible room.

They give us a used room. We had to stay in other hotel.

No manager availble

We really wanted to stay in Dusseldorf but this hotel came up and we didn't mind the 15 minute tram (stops right outside the hotel) to the centre of Dusseldorf. The hotel is really plush considering the price. Good service, clean, spacious rooms with a nice bathroom. It is budget in price so you can forgive the slightly dated decor.
One minor comment is that the room was too warm for us although it was freezing outside so at least they had the heating on.

The pluses: it's cheap. Very cheap. We paid 45 Euros for one night for two people. The key elements are clean: beds, linens, carpets, bathroom.

The minuses: it's cheap. You get what pay for, so none of these are complaints, pretty much what we expected: the rooms have a very dated decor c 1970 (a fantastic LED clock radio built into the wall -- remember those? Only the clock works now). There was/is no air conditioning. Fair enough. but the windows only open a crack, so even with the fan running there was no way to get air going in the room. Incidentally, there was no mini-bar. Just an empty cabinet where it would normally have been. Not that I'm much of a mini-bar person, but gives you an idea of the current state of the hotel.

It is located right next to the tram in Neuss. So if you want to be in Neuss, as we did (had friends nearby) or want something where you can get into Dusseldorf quickly, it's not a bad choice.

Looking back I probably would have spent more (70-90 Euros gets you into chain hotels like Swissotel)) and stayed somewhere nicer. But sometimes you want cheap and clean. If so, this fits the bill.
