The apartment air was so permeated by smoke that I could not breathe without feeling pain in my lungs, even while both windows in my room were open and even while no one was actively smoking in it.
Otherwise, the apartment was passingly comfortable, except for some minor breakdown of supplementary amenities (such as light switches) in the bathroom. I would have enjoyed the stay had my lungs been more tolerant of tobacco smoke.
The lessor worked during the day, and hence had to prearrange a time with me at which to give me access to the room in their shared apartment complex.
The lessor lives in the apartment while you stay in it; the single guest bedroom is supposed to hold two people.
