I arrived late at night on the day of my check in. When I arrived the apartment had a strong smell of old cigarette smoke. This listing is listed as Non-Smoking. I immediately reached out to the host. I opened all the windows throughout the night, as well as spraying the apartment woth a air deodorizer. It did not help, the smell of cigarettes was extremely strong. I have severe allergies and woke up very congested. I was at the apartment less than 10 hrs. I messaged the host and called Airbnb immediately. it has been over 2 weeks and I am still trying to get the refund sorted out.
