I have never stayed in an apartment this dirty. The living room smelled like an Indian restaurant. The toilet had dirt and debris stuck to the surface. The carpets were so dirty that one can see footprints and toothpaste stains. The bedsheets and towels smelled like cigarette. There was dust everywhere. The fridge smelled like old left-overs. I was disgusted by the condition. After I sent photos to Airbnb's customer service, Airbnb gave me a refund without questions asked. The host was understanding and agreed to improve the apartment's cleanliness for future guests.
