I stayed at Morrison House recently while in DC for a one-day business meeting nearby in Alexandria. The location is lovely, on a side street just off King Street near the center of the Old Town district, in a nicely kept brick building with black shutters and a little round portico at the entrance--very Middle Atlantic-looking.
Like a lot of Kimpton hotels, the Morrison House works hard on atmosphere, and mostly gets that right, but gets a few of the nuts-and-bolts things wrong. My room was cozy and tastefully decorated, but the key didn't work on the first try (the doorman who came to help me with it said this was a common problem with their keys), hot water in the shower was lukewarm at 8PM, the air conditioning did not seem to respond very well to thermostat adjustments, and the wi-fi was comically slow.
If these sorts of glitches don't bother you, the place has some genuine charm. The night I was there, they were having a piano bar karaoke session in the dining room, with a two-man band and a DJ running the sound system as a large, convivial group of mostly older patrons sang everything from Peggy Lee to Elton John, some of them quite well. It was fun and different, and almost made up for the lukewarm shower.
