I stayed in the apartment for the month of July '17. I was very happy with the location and the fact that this very safe apartment is in the back of the building not on the Blvd. Beaumarchais side. The apartment is quite large for a studio and the new sofa bed very comfortable (the pillows are a bit flat). I cooked in the kitchen several days a week. It is snug but complete. The bathroom is quite large and easy to maneuver around. In terms of decor, some of the apartment as been updated, like the floors and some of it has a "Golden Girls" quality with dated wall coverings, lights, etc. (The pics depict it exactly though.)
The location is fantastic. You are literally on the border of the 11e and 3e with easy to the Marais and the bustling haut Marais. Merci and the fabulous Maison Plisson are perfect morning stopd for coffee or great salads.
The large size of this place, the ample bedding and closets and its prime location make it a great value. Also, Samuel, my point person was excellent and answered any issues quickly.
Be aware, if you sleep with your windows wide open as I did, the nearby cafes can be loud and the smells from korean spot just below the apartment strong. But it is quieter than other parts of this bustling neighborhood.
Great stay all around.
