We stayed for two nights at the Seikoro Inn. The ryokan is located in a residential area, just a few steps away from the subway station and a comfortable walk to many interesting sites in the area. I noticed that other reviewers pointed out that it is near a major thoroughfare and this is true but the few times we heard noises in our room were not a major issue -- more just a little jog for us that we were smack in the middle of the City.
The ryokan itself has excellent, very welcoming and attentive staff. The amenities are excellent. The room is about a 10-tatami mat size which is rather spacious for a ryokan. Inside the room is your own private bath, robes are provided, tea is brought in every night and as a welcome drink, and the rooms walk out to a well maintained mini garden. It's very relaxing. This ryokan also has a very nice onsen (public bath). It is open and available at convenient hours for its guests.
We ordered breakfast on our last day but because of our budget, we opted out of the traditional dinner. If this is your first time staying in a ryokan, we would highly suggest ordering breakfast and dinner. It wasn't our first time and due to our trip agenda, we only ordered breakfast which was plentiful. We ordered the Western breakfast so no review here for a Japanese meal.
Overall, we highly recommend Seikoro Inn.
