we have 2 apartments in Bulgaria, even though we have the basics in there we are also trying to think what else would be useful to people.
Tin Opener
Iron
Ironing Board
if these were in our apartments this would save a little on the luggage allowance saves taking a travel iron.
Anymore ideas would be great
I have equipped my kitchen with pretty much everything you'd have at home so the 3 items you mention are essentials.
Then I've thought about what you might need on holiday so a cool bag and ice packs, wine cooler (hate my wine warm on holiday!!) but that must depend on how much space you have.
I also provide clocks in the bedrooms, hairdryer, adapter plugs, sewing kit, first aid kit, beach chairs and parasols etc etc.
The only thing I don't provide is pool/beach towels and that's because I just don't have enough storage space but other than that I hope my guests can just turn up with their clothes and enjoy the holiday.
As luggage allowances on aircraft shrink, I think it makes sense for holiday homeowners to provide as much as possible for guests.
Alot of my guests fly Ryanair and lugagge costs can soon add up for a family.
