Valère is an amazing host. He was incredibly communicative throughout both the check-in/check-out process and our days there; he was very helpful and showed us everything we needed to know as well as answering questions regarding Paris, all despite my poor French skills! His apartment is clean, tidy, very well decorated and in a great location (especially for its price!).
On our last day we ended up taking longer to pack up and missing our accorded check-out time (sorry again, Valère) but when he arrived at the apartment he was incredibely comprehensive of the situation and let us finish up without trouble.
Truly, besides being an amazing host, he is an incredible person. I would definitely recommend staying at his place and will surely go back in case we're ever in Paris again.
