It depends on the hotel and the room type. You can see if it is included by checking the text below the room name.
If it is not included, you can roll your cursor over the text in the column called ‘Conditions’ to find out if it is available and if there is any additional costs.
However, if your booking does not include breakfast, but you would like to have breakfast, you can request it during check-in and make the payment directly to the hotel.
This information will also be stated in your confirmation email.
