I stayed this hotel for one night.
The hotel room is very Japanese style and it was like a Ninjya room.
The room had beds with Japanese tatami mat room.
The hotel is located next to shopping arcade (Kami dori) and it is very convenient.
You can walk to Kumatomo castle in 5mins.
You can get a tram from JR Kumamoto station (get off Toricho suzi -8 stops from Kumamoto ekimae), it will take only 10mins but you will need a map.
