Location is convenient and perfect, located at the JR rail/Shinkansen station, with Hiroshima city streetcar station in front of rail station. Extremely clean, awesome beds, spa-like showers, great food, fun bar with Happy hour, easily-accessed smoking area outside the lobby, corner rooms with amazing views, English speaking staff, money-converting machine in lobby, A+ breakfast buffet, convenience stores located steps away in rail station and across the street.
All was basically perfect. Just know that the hotel is NOT "walking distance" to any tourist spots, but IS located steps from the rail and Shinkansen central station and a short walk to Hiroshima streetcar station which will take you all over the city for a few dollars. (¥160 or $1.60 to go direct to Atomic Dome and a museum). Restaurants are pricey but there are 7-Elevens in the rail station for late snacking.
