I stayed there at the end of October for a week. First night was in a regular room; they asked at check-in if I would be willing to change rooms the following night because they wanted to upgrade me. I actually really liked both the base room and the corner suite -- the electronic shutter glass between the shower/bath and bedroom in the regular room was fun to play with, and the bigger room was obviously nice too. No lounge access, and honestly the breakfast was very pretty much not very appetizing (both the "western" and "Japanese" were...very Japanese, but not in the way I'd want.). However, lots of great food options downstairs in the attached mall, and obviously Tokyo has no shortage of excellent food, either. I got a corporate rate booking made before Japan had fully re-opened; prices were 3-4x higher when I stayed.

Staff were (as expected, but always nice) perfect; polite, fluent in English, very helpful, etc.

This would be my favorite hotel in Tokyo with different F&B; as it is, still probably my favorite if the price is <$500/night.

(I also really like the Prince Sakura, etc. near Shinagawa -- really excellent Ambassador recognition, great breakfast, and amazing room, at a wonderful rate; not my favorite location but pretty good.)
