The best thing about the building are the residents and the office staff. The residents are very professional and its so quiet on the evenings. I like the 2 managers in the office; It sounds lame but I actually trust them to enter my apt and put packages in there (lived in places I didn't)
The things I like least are the location. We're right next to a 7-11 that I feel always draws a sketchy crowd and there's not much else within walking distance. A lot of residents in the building also walk their dogs off lease outside so I feel like the courtyard (my view) can get a little crazy sometimes.
All in all though- I won't be leaving anytime soon unless work moves me again. It's hard to find a pleasant place to live in the DC area that doens't nickel and dime you for an extra key.
