I'd say it's perfect for business stay, since the location is just a breeze-walk away from Shiomi Station. The room is indeed small and no space to open large luggage, but it's comfy enough to stay and rest. I have no issue on the eco-friendly policy (you'll get a pet bottle if you put the "no need to clean my room" sign in front of the door, plus the sheets will only be changed every 3-4 days), but it'll be nice if the hotel could at least provide a bottle of mineral water for the arriving guest as well. I was quite surprise when I couldn't find any pet bottle drink or anything similar within my room.
