Check in starts at 4pm; however, when we arrived at 4:30, the room was not ready. We had to wait two hours for the room to be cleaned. After a tiring day of travel, it was not fun waiting until 6:30pm for our room. Once settled in, the stay was quite nice. The train noises are quite frequent due to the proximity of the tracks right by Hiroshima station. However, it didn't bother the three of us staying.
