Like others who have reviewed Old Age, we found the food to be outstanding. We stayed three nights. Breakfast was always the same, with a nice salad, soup, and very good sausage. The bread was excellent, too. Dinner was the same both nights, but again very good, the fish dish being especially delicious.
Also, as others have noted, the room was very small and lacked space for our suitcases. The bathroom was quite possibly the smallest we have ever experienced in Japan - and we lived in Japan before and have been making three week trips annually for the past 20 years. Nevertheless we loved Old Age and are recommending it to our friends.
