Came to DC at the worst possible time (Snowpocalypse 2016!), but it was such a comfortable and relaxing place to stay regardless. It's central to everything you need and spacious enough for 3 people. You can see the metro station from the door and it's only a 15-min walk to the Capitol and 20-25min ride to the airport and Arlington. Kelly even sent my party metro cards on short notice, so we saved money going to and from the airport. During the snowstorm Kelly always checked in with us to make sure we were ok and his family was quick to shovel snow along the pathway leading to the basement apartment so we could still venture outside in the snow. The kitchen was fully stocked with cookware and servingware, with some food in the cabinets and fridge. There's a 27-inch flat screen with Netflix in the living room, so if you're stuck inside like I was no worries about entertainment.

TL; DR: If you want a pleasant place to stay that's accessible to all of DC, look no further. Walkable to the National Mall and tons of restaurants, but in a quiet, friendly family neighborhood.

Caveat: You can really hear Kelly and his family upstairs, so if you're a really light sleeper or sleep earlier than 8pm, you've been warned...
