Host was very responsive. The place was quite easy to find and it's very near the train station (Kita-Ikekuburo). Abt 3 mins walk. From there, only 1 station away to the main line, Ikekuburo, where all the major lines are there and very easy access to go anywhere.
The room was small but still can fit 3 people. Very clean and well equipped with kitchen stove, fridge and etc. Very quiet and peaceful neighbourhood. The only set back are:
1) the lower floor bed, I felt that its quite old and probably it's time to change it
2) The room heater wasn't working well, sometimes warm, sometimes cold. esp at night. Maybe need to be service.
Overall, we had a good and enjoyable time there.
Thank you Kei.
