Lovely flat; I'd gladly stay here again. Beds were comfortable, elevator was very helpful, location is great (both for walking and public transit access), and all the windows provided beautiful views (you can see the Eiffel Tower if you lean slightly out the living room window and look left - and it sparkles every hour on the hour when the lights are on) as well as excellent cross ventilation.
We reached out to the host agency about the shower issue others have mentioned, and they are working on fixing it.
La Maison d'Isabelle is just a few blocks away and has award winning croissant and baguette, and the cheese shop next to it (Fromagerie Laurent Dubois) is one of the best in the City.
We felt safe and comfortable.
