There are many positives about this place: the hostess was great, the proximity to the Metro, quiet neighborhood, easy street parking, grocery store around the corner, futon as a second bed, wifi, close to full kitchen, air conditioning, and washer/dryer. The overall value for the price is great.
There are only a few only downsides: air conditioning was a little noisy, dehumidifier always ran and needed to be emptied, and there was some noise from upstairs (normal house noises like chairs scooting on the floor). However, these are small drawbacks that we found were far outweighed by the positives.
When we come to DC again, we will look to stay here again. Hopefully it won't be as hot next time!
