Yes I am charging more of extra people, cause it is the whole appartment. I did send a message and met a person already. She couldn´t do any changes for reservation and was surprise that she should have informed about number of people. She is paying me now throuhg the bank one night extra of one extra adult, so she got discount on one night and kids are usually free anyway.
Someone from Spain most likely has experienced the same cause the guest said she booked just one person in Spain even though the whole family stayed there.
Maybe I will check out how the booking looks like. What I remember is that it clearle asks number of people who are staying...
