The 89-bed facility, located in the city's ancient Ebrington Barracks, opened its doors in July of last year.
Cecil Doherty, managing director, expressed his "absolutely delighted" reaction to receiving the honour.
"It is a testament to our vision of creating a truly unique luxury hotel in the heart of Derry and to the dedication of our outstanding team, who consistently deliver superb service to our guests.”
