The host seems to be a dishonest person. More than after a month after receiving the first amount of payment the apartment (so it was too late to cancel without loss), the host demanded that we'd pay him not through Airbnb and without any receipt. He just suggested that we leave him cash on the table and close the door after leaving. He then seemed to be disappointed as we assured him that we are on a business visit and left him all the necessary filled and signed papers proving that.
We did not want to leave a bad review for this flat, we were thinking that the dust in the closets, stains on the toilet and the blankets (as well as liquid soap with too much water in it) are not worth mentioning -- but we were resented by the demand to pay additional money for the cleaning. -- And he does this on the last day, in the last hours that we could write a public review for his flat?! Never did the host notify us of any problems with the flat after we left it. The dishes washed, the surfaces cleaned. (One cleaning was already included in the price for this flat as we booked it; no additional fees such as city tax were mentioned). -- Is this a way to get the money he wanted anyhow?
