The sale makes Solstra – a majority owner of Scandinavia's largest exhibition and conference facility the Bella Center – one of Denmark’s largest operators in the hotel, conference and hospitality industry with a revenue of approximately DKK1bn (£107m) annually.
As part of the purchase, Solstra will change its name to to BC Hospitality Group A/S. The Copenhagen Marriott Hotel will continue to operate as normal.
Oscar Crohn, managing partner at Solstra Capital Partners, said the acquisition was part of the company's planned expansion and strategic development to become a "market-leading hospitality company that can further solidify Copenhagen’s position as an attractive destination."
"And we are not finished," he added. "If the right opportunities arise, we are prepared for further expansion. The aim is to be the undeniably strongest, best-run hospitality company in Denmark."
In connection with the Marriott agreement, Bella Sky Hotel will be re-branded as AC Hotel Bella Sky Copenhagen, becoming the first Danish hotel to become part of the AC Hotels by Marriott collection.
BC Hospitality Group also operates the Comwell Conference Center Copenhagen, Copenhagen International Fashion Fair, Forum Copenhagen and International House.
Allan Agerholm, CEO of BC Hospitality Group, commented: "We have a declared goal of being Denmark’s leading hospitality company. With the acquisition of the Copenhagen Marriott Hotel, the re-branding of Bella Sky with the AC Hotels by Marriott brand and the establishment of Comwell Conference Center Copenhagen, we have sent a strong and clear signal to the market that by ‘leading’, we not only mean biggest, but also best, in terms of market-leading brands and quality in everything we do."
The Marriott Hotel acquisition is subject to competition authority approval, a process expected to conclude in early 2015.
