Very cute flat, prime location, wonderful host/communication.
On the top floor with no lift/elevator so you have to be prepared to climb a lot of stairs (we expected this), the room was a lot smaller than we thought it would be (but it is downtown Paris, so this is to be expected), the communication with the butler was a bit odd, making the checkin process a bit strange but nothing to be concerned about. Overall we very much enjoyed our stay here and would recommend this flat. Shoutout to the owner who is a writer and has their books for you to read during your stay.
