Good hoover, kill the mould left by unsanitary house mates, clean the shower, toilet and windows, bin stuff that's just lying about.
Or just burn it down, that'll clean it nicely.
burn mark here and there
As clean as it was when you moved in.
Any tips?
I rented a furnished flat, cleaned it top to bottom, touched up paint, it looked pukka when I left. landlord showed up, flipped the mattress over and showed me a fag burn - I strongly denied it, he said that I didn't tick the box from the initial inspection to say there was a fag burn on the mattress. He kept the deposit.
