Perfectly suited our needs. The room is equipped with AC and a small fridge, and has a bathroom and toilet next to it. There is another room next door which is let out but there was no noise or any waiting for facilities.
The location is right next to the supermarket and the Nippori-Tonei Liner. It's not covered on the JR rail pass, so it'll cost around 500yen to get there and back to the city centre, but it's quick and reliable.
Thao met us with his son as we entered and was welcoming and informative. He also kept great communication up, especially when the Typhoon was inbound!
