Overall, this is a nice apartment with an excellent location. I would use it again but some minor upgrades would make it perfect.
Location: As close as you can get to the mall. You're a block from the White House and a few from the Washington Monument. We walked or scooted everywhere with ease.
Building: The building it's in is first rate. Very clean, well maintained with 24 hr reception and a roof deck
Cleanliness: The unit is very clean. Towels come in sealed plastic bags to demonstrate it. Maybe a little overkill on that
Comfort: Just ok. The beds were a little uncomfortable and couch in the living area sags. There is also almost nothing on the walls (I think there is one poster and it's warped). A little investment here would really make the place.
Noise: There is audible street noise until about 11-12 each night with the master bedroom being a bit quieter. Sirens, honking, revving engines, stuff like that. Friday night was the worst. I dont think it's anything wrong with the unit. It has double paned windows and all that, it's just a function of being in the busy city center.
Weird: When we walked in, both TV's were on Fox News at a pretty loud volume. A little bizarre.
We had a good experience and would probably return just for the location alone.
