Chris is an excellent host. She made us feel welcome on day 1, dug us out of DC blizzards and brought us donuts for brunch one morning. The apartment is within walking distance of the metro and steps from lively 14th st. We fell in love with columbia heights' neighborhood feel. There's lots of dive bars, the best tacos in DC, a little Spanish bakery and a grocery store less than a 5 min walk away.
I wouldn't recommend this place for long-term stays because you don't control the A/C & heat (the main house does), you can't have any overnight visitors (no exceptions) and keep in mind there's no oven but a well-stocked kitchen.
