The hostess did not comply with the regulatory statements of the description and there was evidence that she entered our room without permission more than once. The latter was an offensive action and is against the Airbnb principles due to the fact that we had important and valuable stuff inside.
Additionally, Maria wasn't complaint to the house rules considering the quiet hours since she was bringing guests, as her fellow for example, in the midnight making improper noises we clearly didn't want to listen to.
We strongly believe that the hostess herself hasn't understood the meaning of Airbnb staying for a long time. She didn't let us use or being in rooms we actually paid for after 10pm, due to the fact that she wanted to be on her own. That caused us many problems since we could not use the living room to study after 10pm which was unacceptable due to the fact that we are students.
In conclusion, our hostess behavior was extremely unacceptable and made our staying there unbearable.
