I apologize for the disappointing aspects of your stay. A friend of mine had been living in the flat prior to your stay and I regret to hear that he wasn't able to clean and tidy the apartment in a satisfactory manner. That is of course not good enough and I'm sorry for this.
You are right that it's not a dedicated rental place. You have been living in our private home, which explains the food in the fridge, clothes in the rooms, etc. but I like to believe that this is part of the "Airbnb experience" - it's not meant as a hotel. The sleeping arrangements, lack of TV (and elevator) and stairs were all as specified on the listing but I will make sure to communicate this clearer in the future to avoid misunderstandings.
I hope that – despite the flaws – you had a good stay in Copenhagen :-) All the best
