I stayed at this hotel on my 3rd trip to Hiroshima! Its a good and clean hotel. Location is totally superb, at about 5min walking distance to the Hiroshima Peace Memorial Park. The buffet breakfast was fantastic every day and the hotel personell were always kind (which is a norm in this country). If you want to have some extra rounds after your check-out, you can ask the reception to keep your luggage which they will do without extra-charge. Single room with breakfast cost me about 5,800Yen/day.
They don't have wi-fi, so it is still LAN cable. But the cable you find in your drawer is about 1m long. So, for those like me who like to surface laid on the bed, you can ask the reception for a longer cable. I always travel with my 3m LAN cable, but this time I forgot it, so the reception helped me.
Have a good time in Hiroshima, ladies & gentlemen!!
