The variety and quality in breakfast very low for a 5 stars hotel... No coffee machine available, instead, you have to order it and when it comes is cold and so small, so you have to order again. No basics like eggs or toasts or bacon available, you have to order them and they may take 20 minutes (!) to arrive.... They don't seem to know what a cappucino is (It's NOT a bit of coffee with a huge amount of just milk)...
If you ask for a late check out (just two hours more), they ask you to pay it (first time I experience this in a 5 stars hotel)
As for the cleaning... well, check under the bed when you get into your room...
