Alessandro a San Pietro B&B

The most terrible experience ever I encounter in my holiday, my flight was delayed and the number provided can't be reached, I reached 2 :30 am to Rome and then went to the place, it is a flat in a building no B&B as he put it, my booking was showing still valid in that morning, i booked for 1 day Contacted many time no reply Luckily someone opened the building door and then I was in the front of the flat, called the number in the front of door, no one is replying. Rang the bell and another guest opened the door, I explained to her and she was very nice, told me the key will be in the room. Texted the owner that my flight is delayed, couldn't reach him on the phone as no reply and that I would like to check out at 12:00 rather than 11:00 and that the whole experience is upsetting me I was shocked by a knock on the door at 09:30 am by a guy who doesn't speak English but Italian and very rude and he asked me to speak to Alesandro who spoke to me in English Alesandro who speak English was utterly rude, he said what I am doing in his property?!!!! I said I paid for it and you charged me already, he told me that if you didn't reach by 11:30 he treat it as no show and charges his customer , I was shocked by his ill manner, rudeness and no empathy since my flight was delayed I would have understand if it was 11:00 am and he knock on the door as this is check out time I told him I will speak with the booking people Then another knock asking me to leave and that Italian guy was extremely aggressive and horrible I quickly dressed and left. My whole holiday is ruined
