If you're in a 1 bed flat, would a cordless handstick suit? This one is £85 and gets good reviews... https://www.argos.co.uk/product/4162078?clickSR=slp:term:cordless vacuum:3:83:1
Some of the reviews aren't so good but most are and I suppose you could go up a notch or two on price/brandThat looks just the trick for a small flat doesn't it.
