I don't normally review things, but this place sucked enough that I felt like I should, in order to ward other people off.
There was no single dealbreaker, just a lot of mediocre things that kept piling up. Kinda dirty room, lack of sheets and pillowcases, tiny TV with broken colors, yellowing dryer that didn't dry, draconian check-in procedures not required at other Tokyo spots, kinda far from everything most folks would want to see. It was death by a thousand cuts.
To be fair, the levels of neglect and thoughtlessness wouldn't be so surprising in some other countries, so part of the problem is that every other Japanese spot had led us to expect an elevated level of meticulous care. Still, it sure did bring everyone's spirits down.
tl;dr: even for the price, it's not worth it
