You have everything what you need for short stay and also for the long stay.
Around my house is really quiet but still really near from sightseeing (Website hidden by Airbnb) easy to visit Itsukushima Shrine (Miyajima), and Atomic bomb dome, and the peace park.
The nearest station is Yokogawa Sta., which is 2 stops away from Hiroshima sta.
You will use Futon or double sofa bed. Here is three cats in my house. If you don't mind with that, welcome!
