Decent space, hot jacuzzi and lots of complimentary food and drink = great weekend
4 of us stayed in a 1BR suite (2 queen beds in bedroom) and enjoyed our 2 weekend nights and had a great time. Lots of great points and just a few not-so-great ones.
Pluses: Location is @10 blks from White House and Mall (LIncoln/Vietnam Memorials)--good walking location, and just 4 blocks to metro. 1 BR suite was a bit snug but well appointed, with 2 large flat screens, 3 sinks and a decent-sized bathroom + separate bedroom. Even a window in the bedroom that opened--what a treat! Beds were wonderful and pillows were fluffy and comfortable. Room was a little stuffy so we set thermostat at 69 degrees and stayed comfortable.
Breakfast is bountiful and cocktail hour features wine and beer as well as a small selection of cocktails (including a 'cocktail of the day'). Munchies one night were fresh veggies and dip (yum) plus stack food (pretzels and goldfish). 3 colored tortilla chips, melted cheese/salsa/sour cream, and the requisite pretzels, were snacks on the 2nd night. 
The pool was warm and the jacuzzi was hot and perfect, and open until midnight--a delightful way to end a long day of touring.
Breakfast was decent, with a hot buffet, pastries (rather pedestrian but serviceable), cereals, juices and wonderfully hot and strong coffee. Service was excellent, from bellman to front desk folks to bartenders to pool staff (a woman who swept up the pool area around 10 pm was pleasant, friendly and swept at a brisk, competent pace). Staff seemed genuinely nice. 
At 6pm and at 9am hotel staff give out "fish food" to feed the giant koi. Grab a container and have fun feeding these giant goldfish!
Minuses: Parking garage was 'tight' --almost always full, with small, narrow spaces to park in-if you have a large car or SUV, beware. It's also expensive ($30 per day) but it's impossible to find street parking in the neighborhood, so if you drove there, you have no choice. 
The hotel was very busy, so kids running around and noise at breakfast and at cocktail hour was the norm, as were longish lines for cocktails (evening) or custom-made omelets (boring). 
Apples on the front desk were a great bonus, but one day they ran out and were not replenished :(, and the next day they were mushy/mealy. A nice touch, for sure...just not a very tasty one. 
All in all, this is a great place to stay for a couple of days and the free food and drink were a great bonus. Will stay there again!
