The rating reflects the fact that the AC did not work during our stay. The owner knew that as he said someone was coming to look at the AC and the toilet. I messaged him that no one came and the AC was not working. I fixed the toilet problem myself. The apartment was 81 degrees one of the nights. Luckily the other nights were cooler and we could open windows and doors to cool it down. I did not ask for any $$ back and none was offered.
