We had to cancel our reservation as the apartment smelled of cigarette smoke and was musty. All three of us developed problems breathing and started to feel sick within 10 minutes in the apartment. We opened the window but this did not help as the smell was too strong and could be smelt from every room in the apartment.
We immediately left the apartment and contacted the host about the smell. The host did not reply us. We had to contact AirBNB support and airbnb gave time for the host to resolve the issue. In the end the smell was not resolved. We waited for 6 hours outside the apartment until the cancelation was approved by AirBNB, so we cannot comment on the facilities such as the shower and kitchen amenities.
