OP, it varies from holiday property to holiday property.
According to the Covid-safe guidelines set out by several holiday let advertising platforms, owners are supposed to remove all soft furnishings (!), books, toys, throws etc - i.e. anything that could have been touched by anyone else.
Guests are supposed to strip their own beds and bag the laundry up.
Welcome packs are supposed to be outlawed, along with tea, coffee etc.
However: none of this is law. It's advisory.
I am providing everything that I normally provide, on the grounds that if guests don't want to use a fresh bottle of milk that I have touched while putting it in the fridge, they can just leave it. Ditto cake (sealed), biscuits (sealed), wine.
Teabags and coffee (instant, pods and beans) are all available as normal, in glass jars. The usual staples (olive oil, salt and pepper, a few tins) are still there. Nothing perishable, obviously. People can either use them or not, depending on their preference.
I do not ask people to strip the beds, as they are on holiday and my job is to make sure they have a lovely time (especially when so many of us have had a horrible time). So I do this as normal.
My properties were spotless before Covid, and so I am not making any particular changes there.
One change I have made is that I provide individual hand soaps, shampoo and shower/bath stuff, as I think people probably would prefer not to use a soap dispenser which someone else has used at the moment. Not very environment friendly, but I didn't think I had much choice.
My general feeling, and this has been confirmed by guests who have stayed since July, is that people who are vulnerable are probably not going to be happy to stay in someone else's property regardless of whether the tea bags have been exiled or not. That being the case, I am offering guests exactly the same experience as they would have had before March. I'm afraid it seems you struck unlucky, OP.
@Theimpossiblegirl Those check-in and check-out times are ridiculous!
