The boys had warned they would arrive at 23.00, the hour we had accepted, but instead came after midnight for check in so very noisy. They indicate smells of smoke in the living room, well if people before booking the cheapest place in Milan and offering you more services without any increase, they would see that in the description it is clearly written that in the living room it smokes! The toilet cabinet had actually broken right at the time they arrived. I immediately apologized, but this was not something that could depend on us, things broke and replaced, as at 10.30 the following morning had been done. Did the plumber awaken them? How is it possible if he intercepted at home, when the girls were: one in the bathroom with the door open 20 minutes, the other SITTING, HALF NAKED, on the FLOOR in the corridor; and the other boy sitting on the couch spoke with them. I do not understand why lying, if they had greeted my wife who had gone to work an hour and a half before the plumber arrived; and that's because they were awake and were preparing to get out. Maybe they were annoyed because I asked them to get up in the middle of the passage and raise their things because at midnight at 9 o'clock they were able to dissolve empty and dirty bottles throughout the living room, dressed on the floor, enamels, shoes and tricks scattered throughout the living room. You have to read what you are booking, you can not go for the world with your eyes closed, convinced you have rented a private room in Milan near the metro and 50 meters by bus leading into the city center at € 15 per night. If they had read they would know that the room was IN SHARING and that therefore (even if they were in the room only) did not have the right to invade all the spaces in the living room. As for the sink, we contacted airbnb to point out that the boy was shaving and dropping it into the sink; cluttering him our sink. Not to mention blond hair in the tub. Our family travels a lot and we have never had any complaints from our hosts because we leave homes as we find them.My wife, who is Brazilian and who has known favelas, when she came back from work on Saturday and saw the conditions in which these kids had left the living room, said: "With such guests the favelas seem like a luxury resort , how disgusting!". For two nights, our home has been invaded by the uncivilized, boys who do not even make the bed, leaving their underwear, shoes and socks around, guys who do not even have the good sense of closing the suitcase, raise it and not leave it in half way through the living (Website hidden by Airbnb) have guests every day and we never found ourselves having to be locked in our rooms because they had so far invaded our stay, that our son did not have a corner to sit watching TV or playing. I had never given one star in all the categories before. I am really angry with so much rudeness and dirt, I just need to know that my wife, who is a clever maniac and does the housekeeper, has decided to wash the sheets used by these guests, not at our house, in our washing machine but in laundromat!Another thing I found extremely rude is that they left home without greetings leaving all the lights lit. The night they arrived at 4 o'clock, they left the lights changing to light color, preventing us from sleeping, since, unlike what this guy who in theory studies architecture, there are no false doors, but folding doors of wood and glass (except in the bathroom that is classic and only of wood) from where the disco they were doing in the living room.
