Jon's place is a little gem. A well-kept basement apartment, with a living room/kitchen, bedroom and small bathroom, it's exactly what's needed for a short trip to DC.
It's well located for the subway, and in a quiet residential area - though you're not far from the main street and an up-and-coming area full of bars, restaurants and concert venues. There's also a small corner shop nearby for groceries etc.
Jon was quick to respond to any questions, and very helpful.
