Our experience was very similar to the other reviewers. Matthieu was excellent. He provided us with recommendations on grocery shopping, restaurants, etc. and there was even a Rick Steves Guide to Paris in the apartment which we ended up using quite a bit. The apartment was just as described. It was very well appointed and had everything we needed including a washing machine. The apartment is right beside the Belleville metro station which gave us great access to everywhere in Paris, Versailles, etc. It was very hot in Paris when we arrived (34 C) and the apartment does not have air conditioning (which we knew) so it was very hot. There were fans provided which helped a lot. We also had our two sons with us and they said the Wifi was excellent.
Highly recommend this location.
