The apartment is exactly as what the host has described - clean, cosy, and quiet. It is just less than 5min walk to the train station, where food and amenities are easily accessible anywhere. There is also free WIFI provided by the host.
Communication with Ohkubo-san is effortless, and he puts a lot of thought to ensure that his guests are happy with the whole experience.
Thumbs up for the great hospitality; I will definitely recommend him highly!
