This place was clean and tidy although too small for 5 of us and our luggage. Had an issue with someone ringing the doorbell shortly after we checked in. Owner manual requests not to answer so I didn’t but it made us feel like we shouldn’t be there. I contacted owner who provided a plausible explanation. At 8 am on the morning we checked out, the doorbell rang very persistently for 5 minutes. I advised Yuichi and he responded that it was the next guests and to disregard it as check-in time is 4pm. Just before we left the place at 10, the doorbell again rang. I assume it was again the next guests - pretty annoying.
