I live in a 3 bedroom flat owned by a person who was my roommate for about 7 months. He rented his bedroom to another person for the last 9 months. The landlord stays most nights out of the apartment, but has a key, enters at will and sleeps in the living room at least 1-2 nights a week. He also has not removed his things from the living spaces, and created a private space in a walk in closet for personal belongings. I feel like I should have a rent reduction for now living with additional roommates, he says he never intended to move out and he can live here for free.
