I tended to take one or two trusted kitchen knives with me, and my own peeler wherever I went, but of course these days , cant carry knives around. I agree with you that they should have appropriate size pans etc. If they advertise it as to let for 8 people , they should have the appropriate size things in the kitchen. They wouldnt only have 6 beds would they?
I would have contacted them on the first day and asked them to provide whatever was missing. Whether it was the owners or their agents you were dealing with , they had not checked through properly or thought about this. It is definitely letting down the quality of the place and on basic levels. If it was a pleasant holiday choice, apart from that, I would contact the owners and tell them , and if I was the owner, I would be glad to be made aware of this, and feel that you were entitled to a small rebate for the hassle.
I used to say to friends that they should have a couple of nights sleeping in their spare room, as this would show up any problems like lights in wrong places or whatever, that guests dont like to complain about. It would be a good idea if owners spent a week in their holiday lets and found out the same kinds of things!
