I stayed here twice recently whilst on business trips. On one occasion we held a full-day meeting in the conference room.
The staff were without exception friendly and helpful. Internet is free and it works. Breakfast is excellent – your choice of eggs is cooked freshly for you and there is a good buffet. My bedroom was at the front but well sound-proofed and there was no traffic noise (at the moment there are road works and so there is no through traffic anyway – maybe it will be busier when the works are finished).
The location is pleasantly situated on the banks of the Ruhr (which here looks like an idyllic country river) but of course in winter this cannot be fully appreciated.
The Thai restaurant is unusual but has a decent menu if you like Thai cuisine, as I do. If not, you may have a problem.
The conference room is a bit gloomy, being located in the basement but the basic equipment for a meeting is all there.
I paid 85 EUR for bed and breakfast, which I found OK.
