Shin is always ready to help you. He gave us all information we needed. Great location in a true neighborhood at two stops to Shinjuku by train or 30 minutes walking. It's not far to Tokyo hipster area.
The apartment have three levels. The room is in the high level and you have to be agile person or a "Ninja" to get it. The kitchen is on the floor, it's not practical and getting a bit over use.
