Stay here one night to get the traditional Japanese experience, make sure to book with meals so you can try Kaiseki multicourse dinner, and Japanese style breakfast. It’s in the heart of Gion so you can see old style town homes (machiya). I recommend after one night in ryokan, change to a regular hotel for the rest of your time in Kyoto for a more comfortable stay and closer to downtown amenities.
It’s not a very comfortable stay, but I think that’s typical of traditional Japanese ryokan experience. For example, the summer futon is very thin/hard so I didn’t sleep well. Lots of sitting on the floor or low to the ground (hard for my 60 year old mom). The traditional architecture means many changes in floor height, so going to the bathroom at night is a toe stubbing experience. Lots of rules- changing of slippers, curfew, being careful not to damage tatami with your suitcase or rain jacket, etc. my understanding is this is typical of all Ryokan, just set your expectations accordingly.
The staff at Saka no Ue are really nice and it’s well kept, I’m glad I did it once but also was glad to get a comfortable bed somewhere else the next night.
