I managed to randomly book the “signature family suite” for a night (it was a random week night in off peak season when I was in Kyoto)
Loved the modern Japanese design & interiors, perfect for me as I was travelling out and about.
Particularly loved about this suite, that there was some minor separation of the beds.
Two fluffy futons in the main area (maybe good for parents) then separated by a wooden lattice shoji door, a room with 3 futons - so possible space for ~ 5 guests. However as you can tell in the photos, it’s not separate privacy.
If you want a place with actual separate bedrooms I would look at Mimaru Suites Kyoto Shijo.
