You can't get much closer to the train station than this, it's pretty much on top. As we had a lot of luggage and were only in Hiroshima for 1 night this is the sole purpose we chose this hotel. It turned out to be very comfortable and well looked after- quite a beuatiful hotel with modern furnishings. The 'bell lady' who first helped us was very good with giving directions although I'm quite sure she was waiting for a tip for her services.
The sacrifice you make by staying at this hotel is that the sights and restaurants/ bars of Hiroshima are a street car ride away. Approx a 5 min walk to the tram and then a 15-20 min ride. We were aware of that, but keep it in mind. There is no free internet. The staff were fine yet didn't have that great Japanese hospitality we felt at other places, and some had very limited English.
