I stayed in a single room which was very clean, neat and comfortable, but on the side of a little tight and they also have double rooms as well.
This is very typical of most Japanese hotels for the business traveller but very cost effective.
Free Wifi in the reception and a great Irish hotel next to the reception where the Wifi worked as well.
Great location for business access to the major central business area and for some relaxation and plenty of eating options.
Very short walk from subway station - Nakasu - Kawabata exit 1 or 2. Only a 200 yen cost from the Fukuoka airport which is only 4 stops or about 10 - 15 minutes.
