When I was there in April 2024, weekend breakfast started at 7 am. Weekday was either 6.30 or 7, not sure. By the way in my 4 day stay, the breakfast spread was excellent but unchanged each day so it got a bit boring. I had to leave just before breakfast one morning and asked if I could get a bag with some muffins and yogurt etc. To my surprise, I was told it’s 20 euros per person…I’ve had no such experience of being charged like this at any Waldorf or Conrad or Hilton I’ve stayed at….they usually put a few things in a paper bag for you if you are entitled to free breakfast anyway.
