Loved Penny's apartment. My girlfriend and I lived in DC a few years ago, so we knew exactly where we wanted to stay. Penny's apartment was perfect. Logan's circle is safe, has tons of great restaurants nearby and is very close to Whole Foods. The apartment is about half a mile from the Shaw-Howard metro, but we used Car2Go to get around.
The place is super clean, very comfortable and spacious. The place was nicer than my girlfriend expected after I showed her the pictures.
Penny provides so much stuff to make your stay comfortable. Examples include: Q-tips (not the cheap ones according to Shari), makeup swabs, detergent, toilet paper and some bottled waters.
You can hear foot traffic from upstairs at different points in the day. It didn't bother me, but it did keep Shari V up one night.
