The room was not rented by Hilde herself, but by the elderly parents of her boyfriend. They did not call in advance to confirm the reservation, and I have never been given the personal contact number of the elders. Nevertheless, because I wanted to help them I rented out the room. The room has a key, and can be locked, but they had not asked for it. Instead of a closet there is a clothing rail and enough space to hang clothes. This is teh first time that Hilde used AIRBNB and she appeared not to be familiar with the fact that these are normal houses that are rented out. I have personally called Hilde lengthly apologized for the mistake that my flatmate made. There is no dangerous situation in the bathroom, I used it myself like this all the time. Hilde explained that she had never used AIRBNB and did not know what it was, so perhaps before booking a place for the parents of her boyfriend it is good to find out what it is.
