Stayed for 4 nights at Eime's place and could not have been luckier to have ended up here as I was very sick for the first day. Eime was wonderful about it (I probably created more laundry than any other guest) and took really good care of me beyond what you would expect from a hotel manager - offering extra mattresses and pillows, giving me fruit once I could eat again... This place feels more like a homestay than a hotel! Eime also offers many great tourism suggestions and maps to help you get around, in addition to interesting conversations on many topics!
For the accommodation itself, our room was much bigger than it appears in the pictures. It is traditional japanese style (futon on tatami mat bed, and husk-filled pillows) - these aren't the most comfortable if you are used to western-style thick mattresses and fluffy pillows, but as noted above Eime does have extras that I'm sure you could use if you need it to sleep.
There is no real kitchen to speak of, but you do have access to hot water, a microwave and a fridge for storing or preparing basic food. Eime also offers a 500yen western-style breakfast which is good and very filling (and slightly different each day).
The washrooms are good and clean, and while there is only 1 shower I only had to wait for it once.
The only downside is that the door we had has a ricepaper "window" section which made it not soundproof for things happening in the hall.
