Our family of four stayed four nights in one room with two queen beds. The hotel lobby and rooms are very stylish and the service is excellent. The bathroom was a little cramped.
There are a number of places to eat within 5-10 minutes walk and there is a metro station (Foggy Bottom/GWU) nearby. The Big Bus (hop-on, hop-off tourist bus) also has a stop nearby.
We had dinner once in the hotel restaurant, Jardenea, and were surprised how good it was. If you stay we would definitely recommend giving it a try.
