Yoshihito-san's place is tucked in between two shops in a quiet neighbourhood; initially it was difficult to locate his place but with the help of a map it actually isn't difficult! I soon appreciated the location - it is really quiet so you can have a sound rest. It is also very close to one of the entrances of Shin Nihombashi station, and something like 5 minutes' walk from Kodemmacho Station. Being close to a Tokyo Metro station is a massive plus - it allowed us to take full advantage of our Tokyo Metro Pass which granted unlimited train rides for its duration (we got the 3 day version).
The room is clean and looks exactly as advertised. While small there is more than enough room space to maneuver around - no ninja training needed beforehand! We greatly appreciated the fact that the air-conditioning and the lights always worked for the full duration of out stay. There is a bench and a table so card parties and the like are possible
The toilet and bathroom (they are separate) are clean, well-equipped and functional. We never experienced any faults or breakdowns for the whole week
Yoshihito-san's place offer a consistently comfortable resting place akin to that of hotels at ary fraction of the price. I'll definitely try to grab hold of his place again when I visit Tokyo again!
