It's a hostel so you must to expect that. The bed and shower are great. The host was super kind. The location is perfect if you don't expect to be inside the Louvre. Well connected with the Metro (there's a stop at front of the place) and the distances to every touristic spot are walkable too.
To consider: the place is into a gallery and this detail wasn't tell in the reservation so it could be confuse to get the correct door to it but to solve it I just wrote the host and she answered me instantly. I super recommend the place if you are travelling lightly.
