The Westin Singapore officially opened its doors to hotel guests on Tuesday after an absence of 12 years. Its entrance also marks the first time that a hotel here is incorporated within an office building.

Located on levels 32 to 46 of Asia Square Tower Two at Marina View, the five-star hotel features 305 guest rooms and suites fitted with glass-to-ceiling windows. Its lobby which is located on the 32nd floor is also the highest hotel lobby in Singapore.

The hotel which is managed by international hotel chain Westin Hotels & Resorts under Starwood Hotels & Resorts Worldwide, hopes to attract both business travellers and leisure guests.

Room occupancy is already almost half full for this weekend with locals making up the majority of guests, said the hotel's general manager, Mr Lance Ourednik.

"Singapore remains an important city to Starwood and our prior experience showed us that Singapore is a key travel destination," added Mr Ourednik.

Westin used to manage what was once known as the world's tallest hotel, The Westin Stamford and Westin Plaza, at Raffles City until the hotels' management contract expired in 2001.

It has since been replaced by Swissotel The Stamford and Fairmont Hotel respectively. The brand has over 40 Westin properties in Asia Pacific, with a further 20 properties in the pipeline.
