It was nothing to do with race, it was to do with you inviting 20+ people back to the apartment at 3am.
My neighbours called the police due to the noise and influx of people at that hour.
P. S, you say the apartment didn't meet your expectations, it certainly didn't after your stay. No respect for other peoples property, food stood on the floor and beer spilt on the floor.
Terrible effort by someone trying to put red wine in the sink. Went everywhere and was decided to leave it there.
Mops and brush were in the press in the hallway, next the hoover and ironing board.
I have left you a review also highlighting this so other hosts are warned in advance.
