We booked this room as a stopover between Hiroshima and Miyajima, and while it wasn't super comfortable, it did its job admirably. Despite being a budget hotel, it was immaculately clean and the condition of the building was very good. Our room was spotless, but the beds were pretty uncomfortable. The walls were also pretty thin, so we heard drunk people conversing and laughing until late into the night. Bring your earplugs so you can get an early start to Miyajima in the morning, before the hordes come.
Tips: 1) The staff we encountered didn't speak much English. I speak Japanese, so not an issue for us, but just FYI. 2) There's a giant Gundam in the lobby you should take a picture with. Just do it.
