We really recommend the room we stayed in. It was very clean and comfortable and the owner was very friendly as well. It even included a nice french breakfast with baguette, jam, honey, coffee or tea and juice. The location is also pretty good, a metro station right around the corner and only a nice walk away from Bastille.
We think that it's a perfect place to stay at when visiting Paris for a few days: nice and cheep and centrally located.
