This is (so far) the most spotless clean hotel in Nagoya (maybe in entire Japan as well) I have stayed. In the past decade, I've been travelling around Japan for over 100 times, Sanoniwa is the most spotless clean hotel, not only in the room I stayed, but the spa and other public areas. The staff is very attentive and speak very fluent English. The overall design of the hotel is first-class indeed.
