Stayed here on a Friday night during a quick trip to Washington with my wife. It was an ideal location to Georgetown bars, restaurants and shopping. While you can take a taxi to Georgetown, it is only a 10 minute walk to the intersection of M Street and Wisconsin Ave.
The hotel itself was nice, however, as others have said some of the features are starting to show their age (some touch-up painting and flat screen tvs) could go a long way.
We had the Saturday brunch buffet at the restaurant in the hotel. For $25pp, it was nice, and a deal for what was served. Plus it beat waiting in line at La Madeleine in Georgetown (though if you are an early riser definitely go there).
One of my only complaints was that the parking was $30 overnight. While DC parking has gotten more expensive since I last lived there (10 years ago), $30 seemed more like NY prices than DC. At least my car came out without any new scratches (unlike NYC).
Overall, for $149/night, it was a great choice for hotels. Perfect location if you plan on going to monuments and Georgetown.
