The place was very, very small. It says it sleeps 6, but I would strongly recommend no more than 3. We had 4 people and it was very cramped, if you had more than that there would be absolutely no room for luggage. One of the sleeping spots is supposed to be that black couch in the living room, but it's not a full sized couch, it's maybe 3-4 feet across.
The place was also not as clean as expected. We found some long hairs that clearly didn't belong to any of us on the floors and in the sheets, which makes me think the bedding wasn't changed before we arrived. We found a q-tip under a futon. And the place in general was just a little dusty and dirty in the corners.
On the plus side, Tarou's communication was excellent. Any question I had for him, he answered within 2 minutes. He even came by at midnight and dropped off a fresh pocket wifi in the mailbox when I told him ours ran out of data.
Overall it was an okay stay, but I think I'd rather just stay at a ryokan next time.
