Nothing much to say about this hotel. I guess everything was fine. Haven't tried the breakfast so I can't review it. It's quite a distance to get there from Hiroshima Station on foot (15-20 min) but tram is just at a few meters from it.
The room is a bit cramped for this price, but it may be something about Hiroshima (had bigger rooms in Osaka for the same price or less).
Used it only for one night so I may have missed some things.
