Stayed here for several nights.
Very convenient location with several access options depending on your convenience. It's a 10ish minute walk from Osaka station, a major transit hub, and also close to Fukushima station and Nishi-Umeda station. There is also a bus that goes almost right in front of the hostel. Convenience store just around the corner, about 1 minute away. If you have heavy bags and don't want to walk or take the bus, a taxi is easy to grab from around Osaka station.
Had no inconvenience using the shared shower/bath. There's many stalls and they were never busy at the times I used them.
Service was nice and personable.
Common room where you can hang out/watch tv/eat was pleasant and quiet.
Shoe locker (with key) outside the dorm room as well as small valuable items locker (with key) inside the capsule was available for use.
Comfortable and clean.
