Very good on-sen. Good clean, spacious rooms. First kaiseki dinner I've ever experienced and it was great. Unfortunately, since they've set the standard for kaiseki dinner, the next two kaiseki I had at another hotel at Arima Onsen became dull and tasteless.
If you came here for the onsen, this place is great. However, if you want to come here for other attractions, don't. There is nothing to do for miles around.
