Hello Jeff,
As I live in Kyoto, I haven’t stayed at a ryokan in the city. I have eaten dinner at several though. Below is post about top of the line ryokan in Kyoto.

Good: I used to live in the neighborhood of the Three Sisters Inn ryokan and have friends that have stayed there. It is reasonably priced, friendly and English is spoken by most of the staff.
Sakura Ryokan, near Kyoto Station is not an old, traditional ryokan, but it is built to be like one. I know a lot of people that have stayed there in the last few years and everyone says it is great. New, clean, friendly service and pretty cheap.
Bad: From my personal experience and that of friends, Gion Hatanaka is one that I would avoid.
