Except for the linen that was dirty, the overall experience before that check-out was fine. Position is very good for hanging out some days in Paris, and the apartment with the proper value as per the Paris standard. Then the check-out came.
To clarify, my partner's mother was staying at the apartment, not me. She was 30 mins late for the check-out, and Romain just got crazy. Even if not written anywhere, he started messaging me she had smoked while prohibited. Even if never used, he pretended that she broke the vacuum cleaner. Then, he menaced to throw her luggage outside the apartment (we agreed over the possibility to keep it there until 13, when the check-out was at 10). All my mother plans had been of course disrupted. As soon as she got there to get the luggage, he started becoming racist and extremely offensive (regarding the Spanish origin and distance from the Parisian standards). With my mother getting angry, he started laughing and making a video. Unfortunately, I was not present, and I cannot be completely sure about what exactly happened in that moment. On the other hand, I was the one messaging directly with him, and I first-hand experience his arrogance, racism, impoliteness and rudeness.
