Singapore-based boutique hotel group Grace International has completed the purchase of The Huntington Hotel in San Francisco, California, US.

A spokesperson for Grace said the deal signified "the turn of a new era" in the company's efforts to establish a presence in the global hospitality market. Grace opened its first hotel, The Scarlet, in Singapore, in 2004.

First launched in 1922, the 136-bedroom hotel's facilities include the Nob Hill Spa and a fine dining restaurant - the Big 4.

Nob Hill Spa has 10 treatment rooms, a Zen-themed relaxation area, sauna, steamroom and an indoor infinity pool with views across the city.

The treatment menu includes a wide range of massages, facials and body wraps supplied by Irish brand Voya.
