Location great.
Communication bad.
We found there was no key left for us in the agreed place. We called and messaged several times immediately upon arriving (around 6pm) and we heard nothing from "Philippe". We managed to communicate in the end with the concierge lady (speaks also only french) who lives on the ground floor, she arranged us to get in and get a key. Really disappointing how the host didn't even bother to check if we managed to get in and if we were ok after so many attempted messages and voice mails.
Heating in the apartment was almost non existent, and timed shortly and oddly, no possibility to change the temperature in the apartment. Very cold throughout our stay in early March.
Philippe or whoever actually manages the place or is the host needs to step up and make sure the key is in the agreed place and communicates better even if he is capable to use only one language. Google translate is your friend. Guests need to get in, and not having to knock neighbour's doors to get help. These are the fundamentals of being a good host.
