A very clean and convenient room that is approximately 5-minute walk from Morishita station.
I stayed there with my wife and son and the room was big enough for three of us to stay.
However, two things that I needed to be more careful about was that although there was a picture of a cooking stove, I could not use it for safety reasons. Also, there is another guest room on 5th floor (above our room) that can accommodate more than 4 people and I could hear people walking around and chatting/laughing at night. At one point, people upstairs were too loud and waking up my son after midnight so I needed to go ask them to tone down. It's a really nice apt. but if you are staying with a little child/children, this may not be the best option.
