The most attentive host! Whenever I had any questions, they always responded in less than 10 minutes. This was the perfect size for 1-2 people. It is located in a less hectic part of Shinjuku and literally across the street from the subway entrance. Great location, everything was always 30 minutes away or less by train or foot. There was no sound of foot traffic, but it is located near a major street so you may hear firetruck or police sirens in the middle of the night. Wear ear plugs and you'll have no problem. Using the washing machine was convenient during our stay. Thankfully they sent us a manual on how to use the appliances with English instructions. Very thoughtful and attentive hosts!
