Delphine's apartment is a fantastic place for a stay of any duration in Paris. It is on the sixth floor, and when I first walked into the living room I was struck by the typical yet beautiful "Parisian" view of cascading rooftops, on both sides of the room, and on one side receding towards the Eiffel tower in the distance.
We stayed here in early July. The heat was a bit unbearable, but luckily we spent the time in Delphine's nice apartment.
Highly recommended.
