I booked a night at this hotel as I needed a to stay just one night before hopping into another flight the next day and I chose Ibis.
What a big mistake!
There is actually a Hotel Ibis Dusseldorf Airport, but it is a different hotel completely.
The Ibis Budget Dusseldorf Airport is not just a bad hotel, it is a scam
The hotel is located nowhere near Dusseldorf Airport but in another city called Ratingen, and it takes about 40 euros with taxi to come and 40 to go back.
In the hotel description there is written "Shuttle service" but the shuttle service is Missing in Action.
There is a public bus from the hotel to the airport but you need to know where to catch it.
On Sundays there are very few buses
So you may save a few euros in the room and then end up paying 80 euros to go back and forth from the airport
I suspect they lure customers here using the name *Airport* and then you end up paying more in transportation than in room price.
The room by the way is pretty awful, plastic chair, very basic services, room in March is cold, table to work is really small, noone at the reception for hours, room not really clean, etc.
There are plenty of hotels (Novotel, etc) close to the airport that are much better, you will end up paying a few more euros for the room but you will save 60-70 of euros in transportation.
There is no reason I can think of to come to this desolated and far away cheap crappy hotel.
