The room was fine, I think the price was good for what we got.
About the location: we chose it because it was close to the Gare Lyon and thought to walk there after our arrival, but it wasn't a great idea at night, it doesn't feel very safe. Otherwise, the area surrounding the hostel is fine.
I confirm what other guests wrote: there's some soap (in our case, in a dispenser in the shower), but it's unclear what it exactly is, so I suggest you bring your own stuff.
