The host charged me personally 20 euros for being late. Indeed I told her I would arrive in Rome Airport at 12:45pm. Since the airline company lost my baggage I needed to go through some procedures. At last I arrived in the house at around 4pm and the host said it was too late and too long for her to wait. She charged me 20 euros for being late and refused to get me receipt on such charge. Is such personal charge appropriate? I think Airbnb should respond to me with such charge. Also the host charged me the tax for staying in Rome for 3.5 euros per day (7 euros in total) personally. She refused to get me the receipt on this tax charge too. Why is such tax paid when the booking is made?
