Everything at this location was perfect and it was exactly as described by Laurent, the area is very central and conveniently located to the downtown area of Paris (Louvre is walking distance) and only a few train stops away from the Eiffel Tower.
The flat is situated on a 2nd floor without an elevator which is not the most fun if you're carrying big suit cases. But the majority of flats in Paris are old and do not have an elevator in the building so this is not a surprise.
I was greeted by whom I can only assume was the property manager Dhirar, a gentlemen who speaks both French and English. Very helpful in accommodating us and making sure we knew where everything was when we arrived.
Upon checkout, which was at 11AM we heard a knock on the door at 10:50 and it was Dhirar along with two other people who were about to occupy the flat once we had left. It was nothing short of awkward because I was using the bathroom (doing no.2) when my fiancé had opened up the door. Although all my bags were packed we felt rushed despite having the room for another 10 minutes. And that is the only thing I can say could use improvement that if someone has a certain time to check out do not rush the process and honor the check out time.
