Me and my friends rented this place, we payed all in advanced, but, for our surprise, when we got in the apartment at night, we saw that it was very dirty, like it hadn't been cleaned for weeks. The room, the kitchen and the bathroom (was the worst), the floor, the wall, everything was filthy.
We talked to the owner, that said she couldn't believe it, 'cause she'd cleaned it all. Than she sent a woman that came and in about two hours cleaned the apartment, so it could get a little more decent. We lost all morning of our vacation just waiting for her to clean.
