It was just an unfortunate timing for me that the neighbors were terribly loud. This means that the walls are really thin.
The host on the other hand was very friendly and responsive even at late hours. Accommodated my needs and responded to my noise complaint. It’s unfortunate that the neighbors were constantly loud.
I will also say that the place was dusty and not as clean as picture. Some stains and mostly dust. If you want a clean space you may want to reconsider.
Location was great if you are wanting convenience. It’s in the heart of Shinjuku so many things to eat and shop. I loved the Korean cafes near by.
