We were there two times with your two kids there in our Japan round trip.
It is good reachable with public transportation (JR or Metro) and lies in a residential area. There a lot of restaurants and small shops nearby.
The room has two double beds and a hammock. The room could be locked with an extra key. Everything was very clean and tidy. Hidy labeled everything in English so it was easy to understand and use.
Hidy is a very friendly and kind host. He speaks English very well so there were no converstation problems :)
We liked it there very much!
