My wife and I stayed there five nights, and our son and his wife stayed three. The newer tower where check-in, lobby and restaurants are, and where my son stayed, has rooms that are more western in appearance---at least that was his room on the 11th floor. My wife and I stayed in the older tower. There the bathrooms are very small---one steps up about a foot to get in---and each room has a taiyama eating area. I found our room very comfortable. My wife thought the bed was too hard, but I slept on it fine. Each room has a balcony. If you stay in the newer tower and the weather is clear, you'll get a fabulous view of Mt. Fuji.
We ate breakfast and dinner in three different restaurants. All the food was excellent, and as one would expect in Japan, the service was exceptionally responsive and polite.
It is true, as some have posted, the older tower needs to be cleaned up a bit on the outside so that it doesn't look run down. Nevertheless, our room in the older tower was nothing but clean and modern.More
