I live in a ground floor flat with one flat above me. The architects thought it'd be a great idea to put the kitchen of the flat above right on top of my bedroom. What a clever idea. I've lived here for a year now and as I moved in the people upstairs moved out and it was empty for about 3 months. Chinese final year university students then moved in. On the whole they are fine, not like 'typical' students and make very little noise on the whole. The washing machine makes the whole ceiling shake, so I told them about this and they are good to only use this during the day and not early or late. But....they have a microwave or some other device that they use on a very regular basis that makes a really loud humming / buzzing noise right above my bed. They use this up to midnight / 1 am for periods of 5 minutes up to 1 hour. IT IS MAKING ME CRAZY. I will be drifting off to sleep when I am woken with banging footsteps and then this buzzing noise and I just then can't get back to sleep...hence writing this at gone midnight on a Sunday night. I just don't know what to do...I've contemplated going up to talk to them, but I can't tell them when they can and can't use their kitchen. What can / should I do? I don't want to start dreading going to bed and worrying that I'm going to be woken up, but on the other hand, I don't think I can just ignore this. It's got in to my system. Sleep to a teacher is vital and I'm certainly not one for only a few hours sleep. It's a bit of a moral dilemma....so your advice is VERY welcome! Help!
