In my opinion this owner/representative of this Airbnb, is very unethical. I booked the apartment 6 months in advance for 30 days stay, 7 days before my arrival they wanted to cancel my booking, or split the time between two apartments because the owner wanted to occupy the apartment during my stay. I had no choice but to accept splitting the time between two apartments. Given only 7 days notice, there were no suitable apartments in Madrid for 30-day rental.
Please take my experience into consideration when you book this Airbnb apartment.
