The location of this ryokan is excellent as it's located in Ginzan Onsen, which is a very small and beautiful village, in Obanazawa. The room rates are, in comparison to other ryokans in the same area, very reasonable. We were a group of 5 women and shared a big Japanese style bedroom. We actually booked two rooms with western style toilets but for some reasons they didn't have what we wanted when we arrived so we had to pick whatever they were offering to us. The room we had came with a very small western style toilet. The sink—along with a small refrigerator— was on a small closed balcony and it was pretty inconvenient to use it at night as the weather was very cold and there was no hot water from the tap. The cleanliness of the place in general wasn't up to my standard—and I'm not a clean freak. So, if cleanliness is your first priority then you might not enjoy your stay here. This is a family-run hotel and didn't have many staffs but they did their best to accommodate our needs. All the Japanese meals (2 breakfasts, 2 dinners) we had were acceptable. The onsen room was OK. The temperature of the water in the onsen pool was quite high and it helped relaxing my tight muscles after a long day of walking. I really enjoyed it.
In conclusion, Matsumoto is just an average inexpensive ryokan that, if you want to be right in a beautiful setting of Ginzan Onsen, is the one to stay. We stayed for 2 nights but I think 1 night should have been good enough as the village was tiny and we could cover it in just an hour or so on foot.
