Elsa's and Bastien's appartement is light, big for Parisian standards and a very nice place to spend some time dreaming away on the balcony. It is very conveniently located at 5-10 min walk from 3 different metro lines and in an original, non-touristic neighbourhood. Finally Elsa is really interested in how you are doing and if you need some tips, help, etc. The only minus point that I could think of is that it is on the 5th floor without elevator, but when sitting on the balcony overseeing the roofs and the green square next doors you immediately forget this climb :)!
