We stayed for a week in Bunkyo City and the apartment. Building access was very easy and convenient. The apartment is pretty fine for a shortterm stay. Yet for more than a week I would consider a bigger space. Besides this it is well connected to Ginza and Chiyoda Line, Ueno station is relatively close too. We chose the apartment because it was convenient to take the train to NRT airport. Thank you Masahiro for hosting us!
