It depends on your gite. I only pack beach towels unless no towels are supplied.
If you have a washing machine I may cut down on clothes, we had a week on Provence where I needed two tops each day, everything was smelling of sweat by the evening and we needed another shower.
Change of shoes like trainers, sandals, hiking boots. Long trousers, hoodies and waterproofs.
Toiletries can be shared ideally. If you need more just buy it.
I always take extra Tupperware with me, there is never enough in any holiday let o have come across so far. A smaller coolbox for trips which fits on a backpack with smaller cool packs, the big cooler has the large ones in. Plus a decent pocket knife. If there is really something missing in the gite I buy it and take it back.
Small first aid kit like plaster, antiseptic cream, insect bite relief, painkillers so you don’t have to hunt down a pharmacy.
Tea bags, did I mention tea bags?
