Kuninaka san was very helpful as I had trouble finding the place! I am very thankful for the help he provided in this situation. I had a hang up with my maps which led me walking in the wrong direction for way too long.
The appartment was not more than a short walk from the train staion- I discovered the morning thereafter.
The appartment held the most essential: a prepared bed, shared bathroom facilities, slippers and towels for your convenience. The place does not invite to social interaction and therefore a feeling of privacy needed and wanted. The bathroom facility could need a clean. This is not a room with a view, even being on third floor and with two windows.
This is a place where it will be ok to stay one night as it is closer to Haneda airport than Tokyo center.
