Clean rooms, great location.
My husband and I stayed at the Embassy Row Hotel in Dupont Circle for 3 nights in August 2012. The location can't be beat and check-in was a breeze. They honored my request of putting me on the top floor where no one would be stomping over my head (nice touch!). Our room was very clean and larger than we had expected. The bathroom was small, but the use of space was good. The beds were comfortable and the floor to ceiling windows were great for watching the busy city while sipping a glass of wine. Across the street from our room was the Embassy of Portugal and the Embassy of Indonesia. The neighborhood settles down at night and we had no problem getting a good night's rest. You must go to the Farmer's Market in Dupont Circle on Sunday mornings for breakfast! There are fresh pastries and empanadas for sale, so check it out. 
The Metro is steps away and there is a bus stop out front of the hotel for easy access to everything in the city. There are also plenty of taxis around which were priced very reasonably. You can get to the monuments and museums for around 10 bucks if you don't feel like walking or taking the metro. Georgetown is about 1 mile away, so it's super easy to walk there and enjoy the shopping and restaurants near the water.
The free continental breakfast was better than most places. They had a selection of cheese, yogurt, juices, cereals, teas/coffee, toast, bagels, and danish. Everything was stocked regularly but it was very busy during the breakfast hour of 7am to 10am. 
The hotel has a rooftop pool (which is very small) but the view is awesome and there are plenty of tables/chairs to sit and watch the skyline. The only problem we had with this set-up is that they close that area at 9pm every night. It would be an awesome place to hang out after dinner, but alas, they close it down.
The only other problem we had was an extra "tax" they put on their parking fee. They charge between 35 and 45 dollars a day for valet parking (the parking guys are very nice), but then they add tax to that upon check-out. I thought that was kind of strange and it pushed our bill to $125 to park between Friday evening and early Monday morning. Kind of steep if you ask me considering it's free to park on the street on Sundays. We'll know better next time and will move our car on Sunday.
Overall, this hotel was great for the price. We had no major issues during our stay. It looked like our room had recently been updated, so it appears that this hotel may be on its way to upgrading and making things nicer. I hope this is the case because we plan to return in the future!
