The hotel is in a great location for visiting the city just a few steps from the subway.
I stayed over from December 27 to January 1 in a "half double" (which would be a single 120cm bed) and it seemed quite spacious.
Wi-fi free in the room, electric kettle with tea, bath set complete: toothbrush, nail file, brush, comb and razor.
There was also excellent value for money.
A great experience: if I ever go back to Tokyo, it will be my accommodation.
