The place is close by the Hamatsucho and the Daimon stations so very convenient. There's a really great Australian coffee shop around the corner which was awesome.
The apartment floors were a bit dusty and could be better if it was mopped. Wifi use cannot be for video and heaters cannot be used with hairdryer which is a problem in the winter. The washing machine is on the balcony, which can be problematic to access and the clothes take a long time to dry using the drying rack so I'd recommend installing a clothes hanging pole in the living area.
Kuni is a nice guy who responds very quickly to messages. I think his responsiveness and attitude is a real plus as you can rely on him to resolve any issues in a timely manner.
Overall a good stay.
