For anyone that values a kitchenette while traveling, this place is great. However, I would caution that it is not for everyone. I am reasonably fit, but carrying my suitcase up 4 flights of stairs, in a narrow, winding staircase was a bit of a challenge. The place is older and could do with a refresh, but clean and well maintained. It is a stones throw from the Hiroshima tram system (Honkawacho station). Also very close to Atomic Bomb Dome and Peace Memorial Park. A proper grocery store is within easy walking distance (Yours).
I didn't have any issues with fruit flies (mentioned in another review), but this probably reflects the time of year. The self check process worked reasonably well, and communication via email with the facility manager was good (there is hotel staff on site).
