Good:
#1, size, more spacious than regular Japan hotel rooms
#2, location, walkable distance from Hakata Station
#3, shower, bigger bathtub
Bad:
#1, WiFi, horrible signal
#2, breakfast, just so so
#3, windows, locked so no fresh air or ventilation
The staffs are nice, polite and helpful. Room is clean and tidy. However the design of room is a bit small when you have two check in baggage in the room and nearly no space to walk.
