The place was exactly as described and exactly what I needed as a solo traveler. I was able to check in easily, and there was enough space for my large luggage in addition to the rest of the amenities. The shower was a bit small if you are tall (I'm 188cm), and the bathroom is a bit cramped, but not a big deal - I was getting used to smaller space in Japan.
There's a few awesome cafes right around the place, and convenience stores for everything else you need. It's about a 10 minute walk to each central train station and from there you can get wherever you need to go.
Overall, I would stay there again. It's really nice to have a room to yourself and within a great location.
