A project of Tokyo University of the Arts, Hanare offers five immaculate tatami rooms in an old dormitory house, which has been tastefully upgraded to retain original features such as wooden beams. There is a shared bathroom, but you'll be given tickets to the local sentō (public bath), as the concept is to use Yanaka as an extension of the guesthouse.
Reception is in the nearby Hagiso building, the same location as Hagi Cafe where you'll be served a traditional breakfast.
