We stayed recently and the were a number of advantages: breakfast is a loaded buffet and it was pretty good, the train station could not be closer (and yet the sounds are not troublesome), and the staff is very helpful.
I was honestly confused though as they had gallon size mustard and ketchup next to the omelette station, and I have not seen this done in other places in Japan.
Exit the north side for easy access, when we first arrived we went out the south side, got in a taxi and asked him to take us to the sheraton. Needless to say, we certainly looked like gaijin when he basically drove us around the train station.
MOST IMPORTANTLY: the bed was fantastic, most beds in Asian countries are hard and horrible. This one was lovely.

Very nice hotel at an excellent location and nice as well as spacious rooms. However, the rooms have an open layout so you can see directly into the bathroom and despite the recent opening there were already signs of wear and tear around the desk area and on the walls. Despite being a modern hotel that opened in 2012 there is no WiFi in the rooms.

Stayed 3 nights in November

Pros: next to train station (look for Shinkansen exit), new/modern hotel, free computer usage on 6th floor where you check in.

cons: no real cons. except the shower BESIDE the bathtub is a little odd..

We got a great rate direct from the hotel online for a three night stay. It is adjacent to the train and tram station which is really convenient but we heard absolutely no noise from it. We arrived mid morning by bullet train from Kyoto and took our cases to the hotel to hold them until the 2pm check-in, they had us checked in and in the room within 10 minutes, incredibly friendly and well beyond our expectations. The room was lovely, a great view out over the city, extremely spacious and well appointed plus free internet.

Hiroshima city is compact, we easily walked from the hotel to the Shukkein gardens, castle, Peace Park and museum etc on our first day but if it is too far the tram is very easy to catch back to the station and walk through to the hotel. Restaurants and 7-11 are nearby, or taxi / tram from city are well priced. (For taxi always take hotel card if you don't speak the language).

Transport hub location was very convenient with baggage and for our day trips to Miyajima and Fukuoka (Hakata).
