Sometimes the accommodation may seem available, but it is not possible to book it. This can have several causes. Sometimes two reservations have crossed each other. The accommodation is allocated to the person who has completed the booking process the quickest.
Another cause could be that the website recognizes that there are too many guests in the booking, or that the children are too "old" to be able to use the upper bed of the bunk bed. In such cases, please always contact us by submitting a request in our Help Center, we will be happy to look into the matter with you and help you further.
