After check-in it turned out that the flat is not cleaned (dirty showers, sinks, windows, balcony) and the shower canal is blocked. No signs of any COVID preventive measures could be observed. After raising our concerns, a partial cleaning (only one bathroom got cleaned) occurred around 9pm in the first day, and made the use of the rest of the apartment impossible in.
Moreover, the flat was not in the standard of the pictures in the add, with mushrooms in the bathroom and a broken chair (which then got removed, but not replaced - the host actually threw the chair in front of the house).
Also the entrance to the building was full of water making it dangerous to pass.
The communication with the host quite limited (not picking up the phone even once, communication via whatsapp text).
Once Airbnb Resolution Centre came in, host made false accusations and started to lie.
STAY AWAY!
