The tribute has come from the head of the Irish Film Academy, where the 18-year-old Dubliner was a student.
Ana, who was from Dalkey, became ill during a night out in the city centre at the weekend and died in hospital yesterday.
A post mortem is being carried out today, and tests will be used to determine whether illegal drugs were involved.
Rachel-Sarah Murphy from the Irish Film Academy says Ana's friends have been gathering to remember her.
“Her school friends were doing a vigil in the Mater for her, I know the IFA students were all meeting up this evening and were going to celebrate Ana and they have been tremendous” she said.
“It's been a hard day for all of them – it's been a hard weekend for everybody”.
“Nobody, nobody has anything bad to say about Ana – you can't – she was just one of life's beautiful people” he added.
