Mr. Van den Dop,
when you booked you were few minutes far from the house. Your studio was not ready in few minutes so to avoid you waiting I gave you a free upgrading in a bigger apartment (I do this usually when there is some problem and guests appreciate that!) for the renting with Airbnb without asking any extra price. I would point out that at your request to continue your stay I quickly answered that the apartment was not available for a future rental at that price. So I don't think I disturb you in the evening for a answer to your question.
Of course I cannot give a bigger apartment at the price of small apartment for longer period over the days booked on Airbnb. From the message you wrote it would seem that I did something wrong or a wrong behavior.
