Good location at a great price - very close to subway, 2-3 stops away from museums on the National Mall, 5 - 6 stops from the National Zoo, 5 minute walk to convention center. Fairly convenient access to inexpensive monthly parking options in a covered, monitored garage (2 blocks) booked through another website. Good access to highways opening up day trips to nearby Baltimore and all that is available there. Lots of great restaurants nearby, and located right next to a large, well stocked grocery store. Good public playground was 2 blocks away (great for our kids, age 3 - 5, who joined us on this visit). All this for half the cost of hotel options we explored in the vicinity.
Amenities were exactly as described/pictured, and good communication from host.
Only negative - We had to navigate through large groups of people congregating on adjacent sidewalks in late afternoon/early evening upon return to apartment for the night. Likely due to overlap of our stay with a prolonged heat wave, and the lack of A/C in adjacent apartment complexes. Groups were quiet and did not disturb us within the apartment - a minor nuisance at worst.
Would rebook upon a return to DC!
