In short, I found there are good and not so good things here. I may stay again but only if my next trip doesn't require locker.
The good: It's good for the price. Location is best if you like Asakusa. Bed was comfy and I slept well every night.
The not so good: Maybe it's because of the cheap price, several basic amenities were not initially provided. Towels, slippers, etc are available for rent. It was quite sueprising to hear when the staff explain us to this point, even the staff herself was reluctant to say these things. But eventhough they're cheap to rent, they still disappear/stolen. I went in for shower, left my slipper in front of the bathroom, stolen. Two of my friends hung their towels in front of their bed, woke up in the morning and they disappear.
The bad: no locker for your belonging at all
