A warm throw for the living room,
Something to put my feet up on when I'm sat on the sofa (a pouffe / footstool),
Plenty of cushions on a comfy sofa
Wifi that works
A radio in the kitchen
A clothes drying rack
Decent heating
Local guide books and maps
A cafetiere
Some tupperware tubs
A decent tin opener that works
Big mugs, not piddly little ones
Decent wine glasses
A tray to carry things on
A few board games
Basics such as washing up liquid, wash up sponges, loo rolls, dishwasher tabs, bin bags, tea towels etc
A few store-cupboard essentials such as veg oil, salt, pepper etc are much appreciated - and the knowledge in advance that they are there!
Nice lighting - plenty of small lamps around the place that I can have on or off as I please, including a reading light beside the bed.
If there are steps or uneven ground outside the front door, then an outside light please.
Furniture that is reasonable quality i.e. not the nasty ultra cheap folding dining chairs, or uncomfortable sofas that feel like charity shop reject sofa..
Minimum of ornaments and knick-knacks and no framed family photos
No bossy notices stuck on walls
Privacy. Don't just turn up unannounced to check if things are ok....ring first. I may be in my pyjamas.
Sensible check out time...don't ask me to clean the house and be out by nine am...
At the last cottage I stayed at I much appreciated finding a pack of tampons in the bathroom cabinet as I was caught short, and it was a long way to an open shop...although I suspect that those were left by a previous guest, but I would leave some if it was my cottage.
