I stayed here at the beginning and end of a hunting trip to South Dakota. The hotel is serviceable, was clean and maintained. Most of the hotel is plain, however ownership appears to believe that a (pretty hokey) castle / Renaissance theme is a marketing plus. They offer multiple themed rooms, so if that's your thing - go for it.
The breakfast was again, serviceable, not memorable, and the room is poorly laid out, such that you'll be walking to assemble all the things you need (spoons and forks on one side of the room, knives on the other... REALLY!).
Staff was nice, helpful and freindly. I would (and likely will) stay here again, not because it is great, but it suits my needs, which was to get a good nights sleep and get out on the road.
