Its true I try to cancel because there was 2 booking for the same place at the same time (I rent my flat and a bedroom too on my flat by airbnb) Its not a worrying sign just that kind of moments can happens on period famous like the one you asked. Finally I manage with the others lodgers.
I really found my bed lamp broken!! So yes I claimed for 30€ for this and its not too much! PLease stop lying! It doesn't work anymore.
And yes you leave the place dirty, I ask only 10€ when I rent the place for the cleaning, its not much and its for the sheets, the breakfast stuff I let for you, and mini cleaning.
So when I find my place with the floor dirty everywhere, furnitures moved, bathroom smells bad, trash and bottle to put on the garbage outside, yes for me its dirty and I call my cleaner because I work I don't have any time for a big cleaning. So yes I claimed 20€ more for cleaning!
