Place was decent, and really liked the location since it's just a few stations away from Shinjuku. It's also near two JR Lines. The place could use some tidying though. The cloth cabinet in our room was dilapidated, and for a few days, the washlet didn't work properly. It started working as it should on our 3rd day.
Overall, it was still a nice stay and I enjoyed Tokyo. Miduki was very responsive throughout the stay.
