When we walked in the building it smelled of animals and the apartment smelled like a skunk. A neighbor was smoking pot and the smell was coming through the bathroom vent. We opened up all the windows to air out the apartment. In the morning, the smell had gone until they woke up and decided to wake and bake, but we kept the bathroom door closed to contain the smell and that helped. Once the weekend was over the apartment stopped smelling like a college dorm and we enjoyed ourselves when we were there in the evening.
