I have just had 4 guests arrive with two children when they specified one child. Five guests, children or not, is our limit since we are not comfortable with anymore and would not have accepted this booking if they had told us they had an extra child. This is because our garbage bins get overfilled with nappies and as we let our guests use our laundry facility as a courtesy, find guests with children often exploit this and save all their laundry till they stay with us, even though they are only staying one night and reorganize the rooms to suit their needs, giving us extra work to put everything back when they leave. The said guests asked to use our laundry as soon as they arrived.
Airbnb really need to change their policy so that guests must specify if they have children under 2 even though Airbnb regulation say they should not be charged, so we can have the option to refuse. Under Airbnb, I understand that guests could bring baby twins or triplets who cry all night, constantly use the laundry and overfill the garbage and all for free!!!
Being a grandmother myself there is no way I would book a place and not mention I was also bringing my baby grandson.
We are totally family-friendly and provide toys, highchairs, and cots, which we are happy to do so as long as guests are honest with us and let us know exactly who and what to expect so that we can have the option to refuse.
If anyone from Airbnb is reading this be interested in your comments.
