The location is alright, but not great for long-term stays (more than 2 weeks). I stayed for 3 months, and the building is right next to a voice/dance lesson building that always has their windows open and loud speakers. There was a lot of construction nearby during my stay, so sleeping-in past 9 was never an option. Station was a 12 minute walk.
It is a relatively "residential" area, but not that quiet. Unfortunately, there were a lot of noise disturbances from people yelling outside, and with paper-thin walls, all conversations (inside and outside) can be easily heard regardless of shut windows. The room was relatively clean, and the host was quick to respond.
Please be aware that there is only a dining table and no seat cushions or desk in the room. I was only comfortable on the bed. There were no proper instructions about using water heating, but the host was quick to respond and explain when asked.
All in all, a good place to stay for ~2 weeks. Not worth the high price, however
