Historic, but it closes early.

I go to this post office weekly and it's lovely to look at/appreciate. No issues with heat or air, in my experience.
It closes AT FIVE, and sometimes a minute or two before, so don't try and cut it close-- they will not care, period.
Still, it's the prettiest post office I've ever been to, and the fact that it's in such a stately building makes waiting in line more pleasant. One of the clerks once told me that it's the oldest continuously functioning post office in the country! When I'm getting impatient, I remember that and feel lucky to be there. :)
