We just wrapped up a nice 3 night stay at the RC. The rooms are rather dark and for that reason alone I’d likely not return, but the Tokyo Tower views from the room are stunning. Also greatly enjoyed the fitness center + spa area, breakfast, and the bar. Concierge was absolutely fantastic, as was the staff across the board.
Rooms could use a refresh but aren’t nearly as dated as I expected coming in based on comments on these forums.
