Unfortunately, I wouldn’t recommend staying here.
A lot of things were really dirty or dusty and the bedding was pretty stained. It honestly didn’t seem like anyone had been in to clean or open the windows in a long time.
The air conditioner didn’t work downstairs and barely worked upstairs. The showering area didn’t have much of a proper door where one could change without being seen.
There was rotten food in the sink drain that we had to clean out. And some old food in the fridge when we got there.
The house is also farther from major train stops than seemed to be advertised. To get to almost any location we wanted (Tokyo National Museum, Harajuku, etc) took about half an hour.
