Nice place, but you need work-arounds
I stay here every year for a conference, and I look forward to it. However, you need to know how to work-around some serious issues. For example, the first night I was awakened by loud & sharp street noises that penetrated the 20th floor. Things like truck horn blasts at 4 AM, sirens, etc. The walls are paper-thin, so normal noises from surrounding rooms get through and so do the slamming of each nearby room doors. But, putting the fan for the heater on high drowns that out (messes with the room temp).
First morning my shower drain was slow and the shower was cold. In the afternoon the maint. engineer arrived, apparently summoned by housekeeping (this is a sign of a great hotel). I asked him to address the cold water, and he did. Nice.
Lobby bars are always fun. Champions is a great sports bar and a nice place to watch the Patriots playoff game (unless you were a Ravens fan).
