How to insure second property

cslogg

I live in Hertfordshire and own a one bedroom flat in Aberdeen.
My son is currently living there while at University.I need to take out Home +Contents Insurance for this flat.When filling in the online forms the insurance companies seem to assume that the property to be insured is your home.I do not want to give false information so should I put my name in and the flats address or my sons name?The flat is in my name as my son is staying there rent free although sometimes he does have a flatmate that pays rent for a few months at a time.I am trying the Direct Line site and it does not ask any of these questions.As I said I do not want to give false info but want to get the best deal.Hope the above makes sense and someone can help me.

Thanks
