Basic, reasonably good value accommodation which suited me fine - certainly much cheaper than most places in nearly Dortmund city centre - but just a short train ride away. No frills, but clean and comfortable enough in a convenient location. Breakfast options good. I was able to get into the accommodation even though arriving late in the evening, via the code for the key box which I got from phoning the hotel ahead of arrival. It would be preferable if the booking details (and website) mentioned this so that guests know, but it worked out fine for me.
