flatmate brought an iron, kettle and a toaster. really unnecessary but we did end up using them.
would also suggest just bringing 2 medium sized bowl plates/pasta bowls instead of big dinner plates and small plates.
wouldn't bother bringing any special alcohol glasses eg champagne flutes or wine glasses.
a couple cushions are nice but normally they all just end up on the floor.
also wouldn't bother bringing too many decorative pieces (photos, souvenirs, candles) or books because it makes it so hard packing up and moving out.
wooden and weighted doorstops are rubbish, better off with a cheap rubber one.
people also bring way too many mugs, pieces of cutlery, saucepans, colanders, measuring cups, sieves, unnecessary stationery bits.
you also don't need as many shoes as you think.
