I stayed at here for four months (September to December) while attending law school nearby, and I found the accommodations to be comfortable and a fantastic value. Medea was extremely responsive to my texts, and she addressed all of my requests within hours.
The apartment is the private bottom unit of a row home. I rarely heard Medea in the upstairs unit. The row home is one block away from the H Street corridor, and occasionally the activity from H Street leaked down to be closer to the row home at night; but for the most part, it was a pretty quiet block. I always felt safe in the area.
If you’re staying long-term, the apartment itself is probably best for a single guest, but it can easily fit more. The bed is a full, and there is a pullout couch in the bedroom.
The location is very convenient for long term guests: there is a CVS and a Whole Foods around the corner, and there is a Giant supermarket a few blocks away. It is about a 15-minute walk from Union Station, which connects you to the DC metro (red line only), Amtrak, and MARC. The DC Streetcar (trolley) is also available on H Street. I did not bring a car with me, but parking was not too bad: there is free street parking around a nearby school when the school is not in session.
