Again maybe am on the wrong thread & don't want to open anything up again - as am very new to this site (and have found it a veritable mine of information & recommended it to others i know from other forums).
My husband thought I was mad to want to provide a "welcome pack", but the two rentals that we had this year (albeit friends) really appreciated the gesture. We leave some beers in the frige (went down really well whilst those that the guests had bought from the supermarket were chilling..), some crisps & a packet of pasta & pesto sauce, then if the guests are late arriving for whatever reason they can have a bite to eat when they arrive.
We also provide tea-towels, washing-up liquid, liquid hand soap & a couple of washing machine & dishwasher tablets. This is mainly based on experience & the pain of turning up to a gite for a two night stay & finding nothing of the kind.....
But perhaps I am said in that I love doing all that kind of thing & as for furnishing the house well..........
That's a good one LaLuz!!! 
I bet the spoilsports won't allow for bulk buying IKEA bathmats for my old age though....
