Budget hotel and ordinary service.
I was given a smoking room (requested non-smoking) on arrival with faulty A/C. So I had to survive in cold several hours. I called Mr. Koje of the management company who was very rude on the phone and did not help me. This this is the main reason for giving two rating. However, Hotel did sent someone to resolve it and changed the room.
Pros: On the good side, Hotel is very close to Shimbashi station at a quiet location.
