This ryokan is in a perfect location in a residential area adjacent to Ueno Park. It's around a 10-mintute walk from Ueno Station, from where it is easy to get almost anywhere. The owner of the ryokan is really lovely and helpful. I really wanted to go to the tuna auction at Tsukiji, and based on what I had read, thought I could get there by 4:00 am to get a place; he said that I should leave by 3:00; thankfully I did - by 4:00 it was truly full!
My room was of good size and very comfortable. It was a little cold, but there was a gas heater which warmed the room nicely. The down comforter on the traditional bed was really nice. And everything was very very clean.
My only complaint is that the rooms are quite noisy - the walls are thin, so you can hear everything happening in the hallway. This is, however, to be expected, as it is a traditional Japanese residence and not a hotel. Not a big inconvenience.
