Four Seasons Hotel Philadelphia at Comcast Center

What the classifiers highlight

Occupying the top twelve floors of Philadelphia's tallest tower, the hotel was designed by Norman Foster with sound by Brian Eno and florals by Jeff Leatham. MICHELIN gives it two Keys and Forbes rates it Four Stars, both drawn to the 57th-floor infinity pool that seems to spill into the skyline and Jean-Georges Vongerichten's restaurant on the floor above.
