We saw 3 cockroaches (and probably 2 babies) during 4 nights stay.
I asked the host if we can cancel the remaining days and get refund as we saw two already in first two days.
On their request, I sent a picture of one we killed.
The response:
"You could have found that in the street and says it was on the apartment just because you want to move to another place which clearly seems to be the case.”
They could have declined professionaly without calling me a liar and implying I was a psycho. This is my worst experience on airbnb.
