Great little spot in a really cool street close to Shinjuku! We only used it to sleep as we had full 12 hour days wandering the city so as a sleeping quarters, it was perfect. As Americans used to sleeping on large mattresses, we had trouble sleeping on the floor mats which felt extra thin compared to others we've slept on in Japan. I would recommend buying added cushion underneath or a thicker sleeping pad as it felt like we were on the floor.
