Had a great stay at Derek's place. While we never had a chance to meet him, his associate Dhia was very helpful. The place was large by Japanese standards, but expectations need to be mitigated. If narrow stairs are a concern be aware there are two flights of them here. There are four single beds between floors two and three. Construction could be easily heard from the neighbours but the neighbourhood was generally quiet at night. Air conditioners and heaters are throughout the property. Washer/dryer doesn't work properly, unfortunately. Location was nice and close to the train station. Would stay again if price became more affordable.
