The place is in a convenient location right next to the Louvre. It's got atmosphere and character being in a remodeled attic of an old house.
We were looking for a place to sleep 7 people and it was one of the few allowing for that. The place doesn't really work well for 7 people. There's only one toilet with a door that doesn't lock and one of the sleeping places was a cheap couch with an uncomfortable mattress. Rest of the mattresses weren't great either. The place looks lived in with a lot of host's belongings around. However some furniture is not in a great condition - armchairs are broken, some of the lightbulbs were not working too. The place has acoustic system, music and TVs set up, but only one TV actually worked and acoustic system did not work.
It would work ok for something like a family with 3 kids, I would also still recommend it for up to 6 adults if you are willing to share small beds and determined to stay near Louvre. It gets very tight beyond that.
