This is a very good option for a short stay in Paris, be in a popular area and pay a moderate price.
It is important to note that it is a very small room, it has no windows and that this sofa bed is not very confortable.
However, the place is spotless clean, beatifuly decorated, very well equipped, and the location is fantastic.
I would recommend to a friend, but I would also flag the points I mention above, because I think these things are important to know.
