We are a family of 4 who stayed at Adreinne's place for 5 nights. It was an excellent place to stay and made our family vacation to DC so much better than if we'd stayed in a hotel. For a very reasonable price, we had a very clean 2 bedroom apartment with a full kitchen (with full cookware/dishes/utensils), free washer/dryer, full bathroom with a jet-streamed bathtub (and hairdryer even though it's not listed in the amenities). We have a pre-teen and a teenager and the spaciousness of the apartment afforded everyone a space to hang out together (living room with cable TV) or have their own space after a long day walking around museums.
The location is the best - just 1.5 blocks from the Mt. Vernon Convention Center (on green and yellow lines) with easy access to the mall and 1/2 block to the Giant grocery market. The area is gentrifying and is full of cute cafes and restaurants. It is also super close to Chercher Ethiopian restaurant where we had one of our best meals.
Adreinne is a very good communicator. Her check-in instructions were clear and would respond by text within 5 minutes of ours, even if was just to acknowledge that we checked in. We had no problems at all whatsoever with Adreinne or the apartment.
The apartment building and the furniture are pretty dated but we went to DC to visit the nation's landmarks, not to stay in a fancy room. For the cost and the space, we could not have found a better place to stay.
