As a single traveller, this hotel was a steal. Very reasonable rate for a spotless room. I was on the 31st floor with a gorgeous view over Hiroshima city and the bay. The lobby and common areas are very attractive. The rooms themselves are spacious, bright and very, very clean, but rather dated (fixtures from the 90s, some carpet strains, etc). Bathrooms are very large by Japanese hotel standards and well appointed with supplies.
The staff at this hotel were exemplary: pleasant, professional and welcoming at all times. 4 minutes walk to the closest tram stop, 10 minutes walk to the Atomic bomb dome, 10 minutes walk to Hiroshima Castle. Building is connected to a Sogo department store and underground concourse with restaurants and a 7-Eleven (international ATM machine for foreigners!)
I would happily stay here again on another visit to Hiroshima if the rate were similar.
