This hostel was super clean. Cleaner than three other cheap-ish airbnbs I stayed at in tokyo/osaka/kyoto.
When I went, it was also half-empty which meant that it was quiet at night (aside from a couple of guests who could've been more considerate about not talking in the main sleeping area. But not a big deal--I think they were just trying to get ready for bed) and there were no lines for the shower. I also appreciated how much space there was in the first floor lounge compared to the tiny kitchens at the other airbnbs I stayed at.
There was a bit of a language barrier (she spoke mandarin and japanese. Coincidentally, I'm chinese but only speak cantonese/english) but there was nothing complicated about check-in/check-out.
The location is couple of blocks from two train stations making it easy to get on both the JR line (for tokyo/shibuya/shinjuku/both airports etc) and the ginza line for ginza/asakusa.
