Generally speaking, this was a nice place to stay in DC. It's about a 10-15 minute walk to the nearest Metro Station (Georgia-Petworth). The alley walk is a bit intimidating, but we had no issues with it at all.
Inside, the double bed was comfortable, and most of the space looked fairly recently renovated. The fixtures in the bathroom were very modern-looking and clean.
Temperatures are controlled remotely and Liz was very helpful in adjusting it to meet our needs. A small fan might be a good item to pack in your travel bag to provide white-noise for those who need it to sleep. It was VERY quiet at night in the apartment - which can be good for some and not so good for others.
