I was here in winter (December) so my review is related to this season. The toilet as described is outside the apartment and there is really cold so I advise you to take slippers and warm socks. Also remember that you need to go to the top floor (4) without elevator and this is really hard sometimes :D Also you can't order food delivery to the apartment door (maybe I am wrong here, please clarify from the host) so you will be forced to go down and then up. About shower: hot water enough for 5 mins max. High humidity + cold causes feeling of wet pillow sometimes. And remember that studio is really small and I wouldn't say that it feels comfortable. What's good: location of course, price (related to other Paris apartments prices) and good view to the Eiffel tower from the window. Think twice because next time I would choose worse location but better apartment.
