We left booking our hotel in Hiroshima to the last minute and as a consequence didn't have the chance to check out Trip Advisor before we booked anything - I wished we had, although having just read some of the reviews on here saying the hotel is 'wonderful' I wonder if some of the others were staying in a different place to us?!
I would compare this hotel to Fawlty Towers, The rooms were really shabby, dated and not very clean, The bed was SO uncomfortable that I think we managed to get about 3 hours sleep at best. As other visitors have noted the plumbing is dodgy so everytime other residents have a shower/flush the toilet/wash their hands/brush their teeth (you get the idea) then you hear it! We asked for a non-smoking room but the room smelt like a mouldy ashtray.
We actually checked out at about 7am because we couldn't bear to be there any longer.
We stayed on the 6th Floor but I am struggling to recall the room number to tell you to avoid it! Hideous. Shame, as we loved Hiroshima.
We saw a hotel closer to the Peace Park, just off the main thoroughfare, called Hotel Active which looked great. My recommendation would be to stay at Hotel Active and give this hotel a very wide berth!
