Extremely functional self-contained room (ensuite) downstairs, equipped with a kitchen sink, fridge, all sorts of cutlery, cups and dishes, a Nespresso coffee machine, tea and coffee bags, and the minimalist type of furniture. Guests may go out and come home any time of the day without disturbing the host upstairs.

There is no cooker or microwave but the Musashi-koyama station building and the shopping arcade adjacent to it were always a great source of food . The station is only three to five minutes away on foot.

To get to JR Yamanote loop line, it's only two stations away.

The only drawback I can think of was slow Wifi connection, which is compensated by the good bits as described above.
