This was our hotel of choice for a quick 1 night stop in Gifu.
Positives: new, clean, polite staff, central location, value for money, reasonable breakfast, respite of an onsen
Negatives: tiny room and smallish bed for two people, flat pillows.
Suggestions for future travellers of two - request a twin room with single beds. You will sleep more comfortably. This is a hotel to sleep and that's all. The public areas of the hotel are comfortable and worth exploring. The onsen is indeed welcoming - a nice touch. Most business hotels in Japan are devoid of any style - the Dormy Inn however does have a present-day feel.
Enjoy your travels!
