The appartment was cleaned before, I am sorry if there was a product in the refrigerator that was not fresh. That normally does not happen.
The communication with you was not so easy, you were more then an hour to late on arrival, did not warn us on that and was not picking up your phone anytime I tried to call you. I clearly communicated the shared kitchen situation and that my flat has a common entrance with the flat where florian and teresa live. You locked teresa out of her flat so that she couldnt enter her own flat in the evening and had to sleep somewhere else. She tried to call you, ring the bell and I tried to call you to, but you never picked up the phone. I am not so sure if airbnb concept is a good idea for you, maybe a hotel would be easier.
