About 8 mins walk from local train station. Whole place is so well decorated. Feels dreamy with Ghibli's soundtracks mildly played. The owner speaks great English. Everything is clean and efficient. I stayed in a dorm of 4. The room itself might be a bit small if you have big suitcase. But the space was fair enough for me.
Top floor is where you can hang the laundries. You can see Kumamoto castle from there.
Overall it was a great stay. Also great value for money.
