I now understand why the reviews insist on Nicola's 'likeability', it's certainly to avoid having to talk about the deplorable state of filth in the house. Faeces splashed in the toilet, hair, dust and toothpaste on the sink, soaked bath mat, food left on tableware and cutlery, feet turning black after walking barefoot for 5 minutes, and so on.
I left after 1 night (4 initially booked), after having had the courtesy to kindly explain to her the reasons for my departure (hoping that it would make her react...); I didn't feel like staying the whole stay.
Currently negotiating to get my money back.
I have always given 5 stars to all my Airbnb guests, but this type of situation is not normal.
