Lots of room but rooms are dated and worn...
We stayed here for four nights in September 2012. 
The Good: Great breakfast, nice lobby and atrium, nice little store (the man and lady were very helpful), great laundry facility ($1.00 per load), and nice pool area. We used the computer kiosks for information.
The Bad: No Wifi except in the lobby and the rooms were very dated and could have used a good deep cleaning. Our refridgerator never did work despite mutiple calls and attempts to get it to work. Walls very thin so you could hear the neighbors. Requested a room with a king bed, but was told they only had rooms with two queens. We booked at the same time as our friends and they received the room they requested so not sure what the problem was Were originally given a room on the third floor by our friends, but when we went to that room, they were shampooing the carpet and we were told it would "be awhile." Went back down to the front desk and were given a room on the 5th floor. There seemed a disconnect in the communication between the front desk and the cleaning staff. Living area was uncomfortable to sit and watch TV and relax. Couches are broken down, Armchair had a hole in it, and the coffee tables are way too high to prop your feet on to stretch out. The room was overall a little run down and tired. 
I probably would not stay here again. For the price, I think I would stay closer to the metro and downtown. We paid the same price at the Wall Street Andaz Hotel in NYC and you cannot even compare it to this hotel. Maybe we were spoiled in NYC and so this was an unfortunate contrast. I hear it is undergoing a facelift later this year. Maybe things will improve. 
Overall, the staff was fine and it was a typical embassy suite hotel. Maybe my expectations were too high. We had a great time in Washington D.C. and cannot wait to return again.
