We loved our stay! Regardless of it being on the sixth floor (which was a nice leg workout anyway and added all the more Parisian charm), the apartment was the perfect size for two people!
It was very clean and the light was beautiful! Mohammed also answered very quickly and we could store our bags at his place on our last day so that we did not have to carry them around Paris with us. All in all it was lovely and I can only recommend staying here :)
