We stayed two nights at the Kankaso ryokan. It was an great experience. The ryokan has a beautiful garden and lies next near the temple with the Todai ji with the great buddha. Is is easy to reach. When leaving the train station just ho into the next bus of the inner loop and leave opposit national museum (yobushi garden). Then follow the road to the traffic lights and turn right. Among the shops you see a small sight on the left hand side. Just pass the iron bar gate.
The ryokan is not a cheap choice but with great meals, perfect service and a wonderful bath a "must" experience in japan.
