I didn't actually end up staying here as our SNA did not clear so we cancelled and moved to the Residence Inn Seaport (which we HIGHLY recommend... nicest RI I've ever stayed at, minus the standard Sysco breakfast which is to be expected at RIs).
On another note, we did a duck tour of Boston and the tour guide mentioned "Liberty Hotel blah blah used to be a jail blah blah rates start at $700 a night." I laughed hysterically and wondered where this fellow got his rates.
