There is a very subtle difference between the use of essere and avere for the verb "scendere." When I say "Sono sceso/a" I generally mean to dismount or to get myself down off of something, while "Ho sceso" refers to the action of walking down some stairs or whatever the case is. Verbs that use essere usually refer to a change in bodily state while avere is performing an action. Verbs that can use both, like scendere, have a very slight difference in meaning which is found here.
