I used to live in a small flat and could be guest ready in 30ins to 1 hour. I preferred 2 hours to mess about with laundry and tidy up shelves, hoover under sofas I case someone dropped something and it rolled under. not joking.
Now I've moved to a house (bathroom upstairs so upstairs needs to be guest ready too) and it takes me ages. I need more than 24 hours notice. can't do it. stresses out to no end.
Also do you leave bedroom doors open or closed? I keep mine open because I am worried if they are closed people will guess its a mess!
It can go from beautiful in every room, to a tip in 3.5 seconds with my children too! The older ones are OK generally but the baby and toddler are serial swipers and nothing on any surface or in any cupboard or drawer lower down is safe!
