There was actually no breakfast per se. There was a basket on top of the kitchenette bench including toast bread, coffee capsules for the espresso machine and tea bags. Also, there were plenty of small bottles of orange juice in the refrigerator, two Greek yogurts, and plenty of small jars of different types of jams, honey and nuttela, butter and two large bottles of water.
I can't actually think of something that could have been better.
