We had so much fun at our hotel when we were in DC. It was called the Normandy Hotel and was nestled on a little street surrounded by various embassies. It never felt overcrowded, the staff was incredibly helpful and polite, and I discovered on the last night they had a gorgeous little coffee bar area, complete with cookies! I hope next time I'm in town that I'll be able to visit this little place again. Definitely a cozy treasure. Oh, and the rooms were pretty great, too! I'll have to scrounge up those photos from a different camera.
