I live in a first floor flat.. am always mindful of the neighbours below, dont let ds run in the flat etc.. however they are not mindful of us. They don't go to bed on Friday or Saturday nights until about 5am. All night they are talking loudly, shouting, slamming doors. Last night I got 1 hour of sleep. I don't sleep well anyway. I have tinnitus which is enough of a nightmare without all this. The flat was built in the 1880's so there is virtually no sound proofing. All week I dread Friday and Saturday nights. It's making me ill through stress. AIBU if I went down and told them to keep it down at night?
