(250 reviews) Great hotel/hostel linked to a cafe, shop and cinema. The hotel was great overall, but by comparison to the rest of the facilities, the room felt a touch basic, if perfectly comfortableand spotlessly clean. Great location in Karatsu, within a 5 minute walk to the train station and on a great pedestrianised street full of great shops (mainly with pottery goods). Would totally recommend.
