Indeed Ginza has no pool, the gym seems to be a random after thought ending up being a tiny room with the bare minimum. The bar and the restaurant is rather nice, they have a very generous elite discount on breakfast.
While the pool is not huge at Toranomon it is nice space. The gym is certainly better. Breakfast is overpriced for what it is, the Japanese breakfast is disappointing. The lobby bar is quite nice, though their main bar tender recently left for another venture.
