When I lived in DC, DuPont Circle was one of my favorite spots to go out. This hotel is perfectly located for somebody who wants easy access to "Downtown" DC, but still wants to be in the middle of good dining and entertainment options. It's also very well appointed and has a nice modern design. The bathrooms do have a glass door, so be warned of that if you aren't too, ahem, comfortable with your roommate. I also enjoyed the electronic "Do Not Disturb" function - saves on paper and can't be dismantled by anybody other than you!
The staff was very friendly and check-in was a breeze. Each time I approached the desk, they courteously offered to help me get a cab or directions to my next stop, which was appreciated.
My only piece of criticism - and it's a fairly small one - is that my minibar was not stocked. Normally not a concern, but I had dinner (and several drinks) on the flight in, dropped my bags and immediately met a friend out for more drinks. Needless to say, by the time I got back to the room I needed a snack. Room service ends at 10:30 and the mini bar was barren...in the end, it's for the best because I woke up with no regret of late night munchies, but some crackers may have staved off a hangover.
