I would not say that is easy to communicate with Doris. She is a bit nosy and strange at the same time. I think she wants to be alone and by herself with her things and her lonely life so she should stop renting the room in Airbnb.
The room is spacious yes but is full of Doris clothes in the wardrobes but she is very kind and reserves a bit of space that you can use... .
Doris also not provides a key for the room because she wants to access the terrace to improve her summer tan! So I had the impression that I was not in a private room but in Dori's passage to the terrace! I shared already many apartments specially in Berlin but I can openly say that with Doris was my worse experience.
