This is a classic capsule hotel, with over 400 pods on separate floors for men and women as well as communal baths, conveniently located in Ame-Mura. They're quite used to foreign guests, so this is a good choice for capsule-hotel novices. Despite the capsules being nonsmoking there is a lingering smell of cigarette smoke through the building.
Luggage that doesn't fit in the lockers provided can be held at the front desk (¥200 per day).
