The Royal Park Riverside Hiroshima was one of the strictest concerning Covid prevention, which is a good thing of course. This also meant wearing face mask and a plastic glove when taking something from the breakfast buffet.
Approx 10 min. on foot from Hiroshima JR station and 10min. from a bus stop and the Hop on-Hop off bus stop.
Rooms are a nice size, comfortable and clean, bathroom with all the amenities.
Staff very helpful. Recommended and I would stay here again myself.
