Stewart Taylor, 33, originally from Aberdeen, was found dead at the ground floor flat on Chalmers Crescent in Edinburgh’s upmarket Grange neighbourhood, by fire fighters who had been called to the burning building.
His girlfriend, Lynsey Methven, 30, was rescued and remains in hospital in a “serious but stable” condition after she too was found to be “seriously injured”.
In a statement released on behalf of Mr Taylor’s family, they said: “Anyone who knew Stewart will understand the indescribable loss we have suffered.
“He was deeply loved by his family and many friends, who have all been left completely devastated by his death.
“We will remember him for his positive outlook in life and his desire to do the best in his career as a chef.
“Stewart will stay in our hearts forever.”
A 43-year-old man has been charged in connection with the murder of Mr Taylor and for the alleged attempted murder of Ms Methven.
He is expected to appear at Edinburgh Sheriff Court today (Wed).
