We had cockroaches in our bedroom. We saw at least 3 and the host killed 2 of them. We left the accommodation immediately because it is not acceptable. The host acted very dishonestly and did not want to cancel our stay and refund our money. When we tried to negotiate with him, he threatened to report us to the authorities. Airbnb support also didn't help us, because we only took one photo of a cockroach which was not enough as a prove. Very bad experience!
It is not the whole house, but only an apartment in the basement.
