Ticks all of the boxes, great location opposite Peace Park, friendly staff and a A$12 taxi ride from the train station if you can't be bothered catching a local train.
Close to main shopping mall and many restaurants. Peace Park is very moving and the museum is a must but get there early before hoards of noisy school children descend.
Rooms clean, largish by Japanese standards and has many staff with good English.
Japan is not big on organised tours believing that the transport system is so efficient that you don't need it. It would be helpful though if hotels carried tour brochures in English. Tour operators can be hard to find and hotel staff go blank when you ask about tours.
