We don't take anything with us. There isn't much you can't get at the supermarkets out there (apart from good tea, apparently, but I don't drink it). If there's something you can't live without (such as Marmite

), you might want to take it, but I enjoy trying things which are 'the same, but different'. Having said that, I don't like their whipped butter, but Publix sells Lurpak, which suits me fine. The best bet is to drop off the luggage at the villa, do a recce, and then go to the supermarket. Things which you'll likely need, but which may or may not be there include:
Bin liners - the bins are invariably lined, but there are no spares. Either buy some, or just use the carrier bags you get at the supermarket;
Toilet rolls (there is usually some toilet tissue in each bathroom, but it's likely you'll need some more before the end of your stay);
Soap;
Dishwasher tablets/liquid;
Washing detergent;
Fabric conditioner;
Coffee filters (there are usually some left by a previous renter. You'll also need to buy ground coffee for the filter machine);
Washing-up liquid;
Cleaning spray (I don't imagine many people buy this, but I always do - I like to be able to wipe down daily, in the same way that I do at home. I'm talking about the kitchen/bathroom, btw!

);
Kitchen towel (ditto).
