The new hotel, Four Seasons Hotel Philadelphia at Comcast Center, is being billed as the “the highest situated hotel in North America”.

Comcast Center, which opened last year and has been designed by British architect Norman Foster, is the 10th highest building in the US and the Four Seasons’ lobby is located on the tower’s 60th floor.

The hotel’s 180 rooms and 39 suites are situated between the 48^th and 60^th storeys. All rooms feature floor-to-ceiling views of the city as well as the X1 Video Experience, including 300 channels and a free library of more than 50,000 movies and shows on demand.

Michelin-starred chef Jean-Georges Vongerichten is operating a 59^th floor restaurant Jean-Georges Philadelphia as well as the JG SkyHigh cocktail bar on the 60^th floor.

Another dining option is Greg Vernick’s Vernick Fish, which has been conceived as a “modern American oyster bar”.

Health and wellness facilities are located on the 57^th floor and include a Spa at Four Seasons with seven treatment rooms, indoor pool, fitness centre and wellness boutique.

Christian Clerc, president, worldwide hotel operations, for Four Seasons Hotels and Resorts, said: “We have worked closely with our visionary partners at Comcast and Liberty Property Trust to assemble an all-star team of virtuosos who are elevating Four Seasons service, quality and artistry to new heights.

“Together, we’ve redefined not only the skyline, but the hospitality experience in Philadelphia.”
