Fukuoka Floral Inn Nishinakatsu falls under the Japanese hotel category of 'Business Hotel'. This means the rooms are geared towards single occupants and/or no-frills travellers. Rooms feel small and there's barely any space to walk around after placing your traveller's luggage. On the other hand they also feel comfy and cozy.
Within the bathroom, your standard amenities like bath&face towels, soap&shampoo, toothbrush, shavers, etc are well stocked. Toilet is fitted with electric washlet so first-timers (ideally) should have to familiarise themselves with the device.
The great part of the hotel, though, comes from:
1) staff politeness and willingness to help. They didn't know I could speak Japanese in the beginning and tried their best to give directions in English.
2) hotel location. Within a stone's throw from Tenjin area. Street vendors are plentiful near the canal and river. Also, Canal City Hakata is about 800m away. Walkable.
