Located near Sydney's historical Rocks district and the Central Business District, the luxury hotel houses one of Sydney's finest day spas.

The spa has 10 treatment rooms and extensive wet areas - including a 20m indoor swimming pool, sauna, steamroom and spa pools.

The spa's new treatment menu will be supplied by luxury skincare line Carita and includes signature treatments featuring Carita's Pro-Lift machine.

Brett Butcher, Langham Hospitality Group's CEO, said: "This acquisition signifies the group's plans for a long-term strategic expansion and be a major player in the quality end of the market in the Pacific region.

"We will be investing in progressive refurbishment to position this hotel at the very top of the luxury hospitality sector in Sydney."
