You have two options here, the slightly cheaper Annex or the Hotel, they are on opposite sides of the road.
I stayed in the Hotel it has all that you would want in a hotel, clean, lovely helpful staff and good size rooms.
Close to the Shimbashi station but with no real train noise there is even an underground walk way for when it is cold or wet that links the B1 floor to the station just exit the lifts on B1 and turn left to the end the the corridor and via right.
At 23'000 Yen per night it was an ok rate and I will stay again.
