Koichi was a very friendly and responsive host. He provides a detailed manual to help you with your stay. I am rating this stay at 3/5 because it is a lot more small and cramped than it seems. Though it is listed as being able to accommodate 3 people, I would be uncomfortable with this amount of space as a singular traveler with luggage. My fiancé and I had to take turns to take clothing out of our suitcases. Overall, this is a good stay for someone who is a single traveler with a backpack.
