I was staying for 1 month though, it was very nice place, hence following reasons;
1. Cheaper supermarket (Gyoumusuper and Donkihote) than other Japanese supermarkets are near ( 7 mins by walk)
2. Truly 5 mins from Heiwajima-Station by walk
3. Large park is placed near ( 3 mins by walk)
4. Car sharing (careco) and bicycle sharing service place is placed near ( 5 mins by walk)
5. Owner (Mitsuru-san) gives response swiftly anytime
6. So clean room and large couch which can be used as bed also
Thanks for your care, Mitsuru-san.
I was really lucky to stay this house.
