Noisy squatters that can just carry on as they please

After asking the security at 22:00 to ask the squatters outside our window to keep quiet and waiting for them to do so. Nothing happened other then the squatters getting louder. Then at 23:00 I asked them again. All they said. We not in charge of that section. Then at 00:00 I asked again and made a scene. Still nothing. At 00:30 went to look still nothing. At 00:45 after loosing my sense of humour eventually they did something. Ridiculous. Coming here for a peaceful nights rest you get none!!! I will be asking for my money back.
