I had the smallest room of any of my 12 stays in Japan. The room was tiny, badly lit, and grungy - morelike a capsule than a room. Also the bed was hard as a rock, and the pillow (one pillow, one towel), was so hard, i woke up with all of my neck muscles screaming. The che kout time is 10 am, which is early, but trust me when i say that you wont want to linger.
The staff here was very friendly and helpful, but the cleaning staff was scary looking and rude.
The location of this hotel was good.
Overall, I would not recommend a stay at Hotel Musse. There are roo many options in Ginza to stay in this place
