I stayed in multiple superhotel in my life and the service here is the best. The air con in my room is super noisy and the staff are very helpful to rearrange the room.
The hotel is not quite "ekimae" (in front of the station), but it's only a couple of blocks away. Friendly and solicitous staff went a long way toward making my stay enjoyable. And the price-performance is good, especially when Hiroshima hotels are full or crazily priced. One thing: I had to book a "smoking" room, because all the non-smoking rooms were booked. There's a reason they were all booked, Japan hoteliers: no one wants a smoking room, not even smokers. End smoking in hotel rooms!
