We stayed in the one bedroom suite. Loved it. The only problem is that the couch in the living room was the most uncomfortable piece of furniture I have ever sat on. My husband felt the same way. The chair was OK. I actually sat in one of the chairs from the dining table. I do love the bathrooms/toilets in Japan. The toilet in the suite bathroom had a motion sensor. Not sure if that was an "upgraded" toilet feature but in all the hotels I have been in in Japan, that was a first.
Have to agree that the lounge was the best I have ever been in of all the Marriotts I have stayed at. Service staff for wondeful. One evening we got back to the lounge late, after drink service, but the staff still got us our nightcaps
