Ritz-Carlton Kyoto is great. Elite treatment is above and beyond brand standard too, with breakfast for platinum members and above. The activities they offer are great, and many are complimentary even when they include transport by car. I'm personally a huge fan of Suiran Kyoto having stayed there three times and having received great upgrades for all of them, but the hard product of the standard room at the RC is equal or better than Suiran's deluxe room which is two categories above the standard room.
