Staying at a traditional ryokan was definitely on my Kyoto must-do list, but then I discovered how expensive they are. The Yachiyo was one of the more reasonably-priced options and the photos on the website are lovely, and they even seemed to have budget rooms that were smaller than the rest and described as "with a washroom,without a bathroom".
On arrival, our room was set-up for day use with mats on the floor and a wooden table in the middle and a pot us tea to welcome us. There was a tiny TV (don't think we even turned it on), a phone, a sink, a small sitting area overlooking the garden, and a tiny bathroom that reminded me a lot of being on an airplane.
What it lacked was a shower or anywhere to wash up! There are literally no showers anywhere in this hotel (something I really wanted to do after the long flight to Kansai, and then the train ride to Kyoto) - the cheaper rooms only have access to the shared baths and it's a little odd to be washing your hair in front of other people. It was fine, just a little unexpected :) Similarly there is no bed - the staff come in the evening and set up futons for you to sleep on.
I did get a chance to peek at the more expensive rooms (even our budget room was $200), and they were gorgeous with screens opening up into the gardens and their own bath tubs.
One night was enough, but I'm glad I tried it.
