Honestly this is one of the nicest places I've ever stayed. It's cozy and warm and very spacious, with lots of little touches that you miss when you're away from home but make a vacation stay extra comfortable when you have them; the mark of a thoughtful & kind host! Also she is lucky I dragged myself off that couch to get myself home, it is very very comfy.
Dee is very responsive to questions, though I didn't have many because her instructions were so clear & concise. Check in & out was very easy.
The neighborhood itself is chill, I came back late at night alone every day I was there and had absolutely no trouble. It's one bus stop away from the Potomac Ave Metro stop and while me & DC buses have had our differences in the past, this time there was no drama and they ran perfectly. I also didn't notice any unusual level of noise, no more than you would get in any other centrally-located city apartment.
All in all I really think Southeast DC is a secret I'm happy to keep--but this place shouldn't be one, it was wonderful and easy and run by a fantastic host!
