After we rented the place the owner sent the message that when we arrive we have to pay an extra 50€ to pay the cleaning service after our stay. We agreed though it was a big money, because by that time all other places were booked. The night before we left the owner sent the lady that should clean to pick up the money and we paid. Before leaving we left the house the way it was, just left unwashed dishes and some garbage in the special bags, because there were no a garbage place around the place. But we felt ok, because we paid the cleaning lady.
Next day after our stay we got an SMS from the owner that we left a disaster in the flat and very dirty etc. And the only thing we left were bags with garbage and dishes. Then we received an SMS that we have to pay an extra 200!!!€ for cleaning or he will call police! We are considering it as an extortion, because what he is saying is a lie, especially because we paid for the cleaning. Please note this because it could happened to other renters as well.
