It is a nice apartment and on a really great location! Alain is such an amazing host we can ask for! He responded to us quickly and nicely even at the late time of the night when we had the problem with doors (not used to it yet)! The house is cozy and clean! I love the view from the window! It's priceless! The stairs are hard but taking it as a good exercise for our vacation, so it worked well!
Side notes, I would love it more if the internet is faster! The shower door may be the issue but that has been over Europe, so try to make it work!
Otherwise, this is a place to be in Paris, highly recommended!
