It's been difficult for me to leave comment about this trip. Yuwei is indeed very responsive proactive considerate host.
..I think his friendly attitude and the location are only two I can truly recommend. the location is bit off the main road "Aoume Kaido" and so close to Shinjuku center. Can't complain at all.
The cleanliness is what I am concerned (but i think it can acceptable for some young people who don't care much) The room is quite dusty, the cupboard under TV is broken, the kettle seems to be missing during the trip (or I just can't find it because it's well hidden)
The first day when I spreaded the blanket I found suspicious short curly hair...
I managed its because of Yuwei's busy profession and my trip being at the peak of whole year.. that the cleaning service was not able to be done up to normal standard, perhaps.
Later I found an old comment said the keypad for the building does not work... and it really didn't. but its the property management not Yuwei's fault.
