I think she's around Karen age.

At the end of the Novel 3 (I don't remenver if is on the anime), M explain how he and Elsa start dating. At that moment (that is before november 2022, the SAO incident) Elsa works as a waitress (so she has the legal age to work, so she have around 16 years). At 2026 she have around 20 years.
