Where we are currently staying. Apparently it's pretty well known cause it's one of the few surviving traditional Japanese inns in Tokyo. Most are just run like a hotel but have Japanese style rooms. This is the whole deal.... meals in your room, shared bath (not what you think, this is like you get to use a giant super awesome shower room & jacuzzi thing all to yourself, you just reserve the time you want), bla bla. Pretty cheap too.
