Walk into this downtown hotel's art deco lobby, with an original terrazzo floor and pressed-tin ceiling, and go back in time to the 1920s, when the hotel was built. Take the staircase to a vintage room with hardwood floors and antique or reproduction furnishings and a claw-foot tub. Even the modern rooms have a retro look and feel at the Armstrong, which is on the National Register of Historic Places. The beds are made up with cotton sheets and feather duvets and pillows, and each room has a writing desk and coffeemaker. For a longer stay, there are two studio rooms and two apartment suites, all with full kitchens.
