Simple guesthouse that has beds and decent size shower rooms. Unfortunately, there is only 1 toilet on the 3rd floor on the female dormitory level. I am very familiar all sizes of futons (mattress) in Japan, but the futon here seems to be very very thin. So, practically you are sleeping on the wood of the bunk bed. Tatami is more comfortable than wood, btw.
I noticed staff/manager the woman from Taiwan ignores some guests including me depending on her mood or unless she dislikes those customers. However, that is not professional.
Just a fair warning, if you have heavy or big luggage, there are too many stairs to go up and it will be a challenge.
