DoMo is conveniently located in Shinjuku. It's a short walk to Shin-Okubo station and a pleasant walk from the main Shinkuku station. Late night and 24-hour tonkatsu, ramen, other restaurants, and convenience stores are in the surrounding area. It's far enough from the heart of the city where you feel away from all of the noise and activity, yet close enough where you know you can be there in a few minutes.
Our room was sparkling clean and had all of the amenities that were mentioned in the posting. There was nothing we didn't expect, in terms of the size of the living area, bathroom, and kitchen.
Communication with the DoMo team was excellent. They responded to our emails and questions well within 24-hours after our initial messages, and they provided in-depth PDFs and instructions that helped us get to our room, to the DoMo cafe, and the like.
All in all, I would highly recommend DoMo. If (and when) I ever need a place to stay in Shinjuku for an extended period of time, I'll definitely reach out to them again. Thanks for a wonderful stay!
