We stayed there as a family of 5 including our 79-year-old grandma. The hotel was smaller than we thought, but the service is superb and the rooms/facilities are very clean throughout. We didn't have any problem with the cleanliness. They offer beautiful onsen which my grandma even enjoyed. Very clean and pretty. The location was great too. Easy accessible to other parts of Fukuoka. The only downside might be we have to book 3 rooms for 5 adults and the bathtub makes it difficult for grandma to take a shower. There's also noise at night in every room which is quite irritating, but it might be due to power/electricity because it was near the fridge. We didn't book breakfast beforehand, so it's also quite difficult to book breakfast on a daily basis. The breakfast was Japanese style and tasted good though.
