The apartment was clean, comfortable and in a perfect location. However, the heating was not working in the bedroom. After informing the owners, hoping that they will fix the problem because the weather in Paris was cold, they did not react as expected. They were not helpful or understanding. They did not send anyone to check the malfunction. Instead they were trying to convince us, by sending us statistics, that the temperature of the apartment was fine and that the average temperature in the bedroom should be around 15-16 degrees. The apartment on Airbnb was advertised as a functional apartment and that was not the case. The environment was unpleasant and we could not sleep due to the cold. The behavior of the owners towards us was unfriendly and rude, which made us feel even more nervous and unwelcome in their apartment. Our overall experience in their apartment was negative.
