My mum and I shared this space, which was beautifully designed and a good location to the Eiffel Tower and metros.
The sofa bed was not comfortable and there was not a lot of floor space so if you stay I recommend for couples or single person.
Also, the space is smaller than the photos suggest and the courtyard / entrance opens to the back of a restaurant and bin area. There are no windows only the courtyard view to this area.
