I thought this hotel was fabulous.
The rooms are small - the bed took up most of the floor space, there was also a desk with mirror and chair squeezed in there, but I didn't spend much time at the hotel so didn't have a problem with that.
The breakfast was fabulous and included in the price, buffet style with a mix of both japanese and western foods (cereals).
There is a bus stop directly out front of the hotel which takes you everywhere you would want to go as a tourist in Hiroshima.
The website is in Japanese but you can send them an email (in English) to make a reservation.
I would definitely stay in this hotel again.
