Was a little concerned about this being a backpacker hotel however, this is a great place. Clean, friendly and well equipt. Even during the recent hot weather, staff were falling over themselves to get everyone fans to try and keep cool.
We had private bathrooms overlooking the atrium/bar so noise was an issue as the music went on until 3am. Hey do provide earplugs however, as I have difficulty getting these to stay in my ear, they weren't much use. I would suggest that the hotel does make it clear that on some evenings there will be loud music until very late at night/early morning. That said, it was a Saturday night so maybe we should've expected something like this.
All of this aside, this is a great place to stay and visit Paris.
One tiny criticism would be that although we both had private bathrooms, only one of us had soap and shampoo provided. Not a major issue, just a comment.
