I enjoyed staying at Koko hotel Hiroshima. It was in a super convenient spot, close to the station and walking distance from historical sites, parks and restaurants.
Staff were polite, friendly and were able to speak some English when my Japanese wasn’t good enough.
The only thing I would suggest would be a bigger pillow. And maybe an extra one too. It’s possible that one was available but I didn’t ask. I would definitely stay here again.
