The apartment has nothing to do with what it looks like on the pictures - different (uglier and older) furniture and much more run-down, dirty and broken! They agreed to let me leave my suitcase at the apartment 2 hours before official check-in. At that time, it was still messy and full of of garbage from the people that stayed there before. I talked to the lady on the phone, she said it‘s already clean, I said obviously not because I just left my suitcase there and it was still dirty. She assured me they would clean it right away. Came back at official check-in time and it was still in the same dirty and messy state! Wifi was also not available although I specifically asked for it before booking. Thankfully Airbnb helped me cancel the booking.
One thing about the host: they are a rental company and rent out several apartments in the building. There is a sign in the elevator that says they are causing a lot of problems for madrileños living in the building because they constantly leave too much garbage so that normal tenants cannot use trash bins anymore etc. Shows what type of company they are.
