I hate, hate, hate it when the property owners have so obviously come in and cleared away all the things that previous tenants have had to buy, e.g. dishwasher tablets, washing machine liquid/tabs, conditioner, cling film, foil, washing up liquid, olive oil, flour, pasta, rice, salt and pepper etc. It's so petty and it means that every tenant has to pay an unnecessary amount of money.
If tenants leave stuff behind because it's not used (apart from fresh stuff, obviously) then why not leave it for the next tenants?
Best place we stayed was where they had cupboards full of basics, such as pasta, flour etc, with a note saying that we were welcome to use these things, but just to replace them during the course of our stay so that the next tenants could benefit from this too.
They even did this with gin/whisky, etc!
Please make sure that the washing machine/dishwasher/microwave/cooker is working.
And another pet hate (sorry if this is turning into a rant!) is when the lighting in the kitchen is insufficient - bulbs blown and not bright enough to see what you're doing.
