This place was modern, clean and NEW (exactly as-described). It was a .4 mile (about 6min) walk to the L'Enfant Metro Station, which basically connects to everything--super easy to get to Capitol Hill or the National Mall REALLY quickly from that station. The price, while expensive-ish, was totally worth the location and the modern amenities of the apartment. We used the Queen bed AND twin bed in the main bedroom and there was still plenty of room for luggage and walking around, and the pull-out couch was easy to use. Note: the pull-out couch isn't your standard type with the metal frame and everything - the back cushion becomes the other half of the mattress, if that makes sense.
Keep in mind that you are in a basement apartment in a city, so you'll hear noise from upstairs and street noise. It's unavoidable. But with that aside, the apartment itself was great. Would stay again, and would recommend to a friend.
