I stayed there first time. I always stayed Shiodome Royal Park Hotel. One thing I didn't like it's because of receptionist. When I checked in, the guy asked me if I want to up-grade the room what can see Tokyo Tower with 2000yen/ night because the day the room was still not full. I thought usually five star hotel offers good room even though the customer does not ask for. That will make customer happier instead of asking money for up-grade. I guess this hotel service is like this level. Other than that, the staff was very friendly and good attitude.
