The location is on the outskirts of Dortmund, very quiet and lots of green.
The room was spacious but poorly designed. Just a small clothes rack in a very dark spot. No drawers. Seems like they are expecting only traveling salesmen staying one night. Lighting in the bathroom also in the wrong places. Very few toiletries and the cheapest they could get.
Service is non-existent, be prepared to haul your luggage to your room by yourself.
Room service comes from their supposedly better restaurant. My wife had spaghetti bolognese which was pretty tasteless. And there was still cooking water on the bottom of the plate underneath the sauce totally ruining the already poor dish.
We had dinner at their other restaurant, white asparagus which was in season. Unfortunately, it had lost most of its flavor due to overcooking. We had ordered one serving pf asparagus to go with scrambled eggs and Büsumer shrimps. The eggs were also overcooked and the shrimps were missing. When we complained, they brought us a serving of shrimps separately which is not the same thing as the advertised dish at all.
After that, we didn't expect much for breakfast. The bread was ok, very limited choice of cold cuts and other stuff. The smoked salmon was squeezed together in a tight dish and you had to rip it out. I have nowhere seen such an appalling presentation.
The staff, especially the kitchen staff seem totally unmotivated and poorly trained. In view of the quality of the room, almost non-existent service and the lousy food this place is hopelessly overpriced.
