Mila’s place is in a charming part of DC out of the mess of the National Mall. That said, DC is very walkable (for folks who are able to walk for 30 minutes to an hour comfortably). I’d recommend nearby rock creek park with a stop off at the zoo.
Mila is a gracious host with a lovely home. She may not respond to messages quickly, so I would recommend messaging early. I tried calling via Airbnb but the voicemail listed a man’s name. If you message about a day ahead (of arrival, departure, if you make other breakfast plans) then you should be fine. She genuinely will make you breakfast and enjoys chatting with guests, so either build that in or communicate clearly about your timeline.
Would definitely recommend, especially if you’re looking for homey comfort.
