We booked a private room for 2, it was very nice. It felt very safe. The location is great , 3 min walking distance from tsuruhashi station. There is also a convenience store downstairs open 24/7.
You are not allowed to eat /drink in the room. Also , you have to be quite in the room since its a dorm.
The biggest con is that there is no elevator, we had a huge bag to carry up to the second floor!
You can always ask help if needed.
