As advertised, the trains do pass frequently and they are indeed loud and shake the building somewhat. I got used to it pretty quickly and was able to sleep without a problem, but this may be an issue for others.
The location is fantastic. Takahatafudo is a wonderful little town with lots of great food locations and a beautiful temple that often holds festivals with stalls and games. The room itself is situated very close to the train station and is a breeze to walk to.
My only complaint is that the walls are quite thin, and the room next to me at the time seemed to be filled with extremely rowdy foreigners who crashed around and shouted through to the AM hours some nights which was quite annoying.
Overall I am very happy with my stay, and Rickie was a wonderful host that responded quickly to any inquiry that I had.
Thanks!
