We have chosen to keep our B&B small-scale - max 4 adults, and only offer it to adults (infrastructure and layout are not suitable for children).
Flat Aline and Suite Florentine are part of our house.  So there is a homely atmosphere.  Guests certainly have plenty of privacy, but you are still asked to be considerate of your fellow guests and owners.  Guests are not supposed to invite other people to our B&B.
