Chef Marco Pierre White will also open his second rooftop Steakhouse Bar & Grill on the roof of the hotel, serving classic English and French dishes.
The property will feature 122 rooms designed to highlight three recurring themes - made in Wales, industry and music. An onsite fitness centre will be open to guests.
The hotel is in close proximity to Cardiff’s business district and provides easy access to attractions such as Cardiff Castle and the Millennium Stadium.
