I bet you thought you were coming to a warm country and now you're wearing a coat in the house! I know, it's a tad chilly when the weather cools and you find that no central heating and no double glazing 'because we have a mediterranean climate' is a bit odd. We'll all be changing over to our winter curtains like Grandma did and snuggling up under a blanket on the sofa.
I suggest put another cat on the bed ............. or
We had a wood burner which was lovely except for having to clean it so now have a gas equivalent which is fabulous and the gas bills aren't too bad. You can also get reverse cycle air con and heating which I'm not a fan of but other people love it.
