I've been a guest at this hotel for several weeks, and it has generally been a great experience. The staff is friendly, especially after they've seen you around several times. The corporate rate I have gets me access to the Club Lounge, which provides a decent breakfast every morning. The staff there are outstanding. The reasons I've only given 4 stars are that (1) the breakfast options in the lounge never change, (2) the food at the bar and in the restaurant is overpriced, and (3) I've had several instances of my key cards suddenly not working (despite having kept them in a pocket by themselves all day).
