Good to near Okayama Castle and the Garden. Just next to a supermarket which is for local people. Hotel staff was helpful too!
Yet, it's quite far away (15-20min walk) from Okayama Station though you can spend some to take the bus. The room for 2 was quite small. Yet, we guess it's the same for all hotel rooms.
Anyway, the price determines the quality. You may spend more to have a better option.
