SERIOUSLY???? :-) i am so glad i tried this experience of renting a room for the first time because it is far better than booking a hostel or hotel when you have a small budget. Robin helped me finding my way from Union station and also from Dulles for my friend coming from France to visit DC. It felt good to sleep in a house and a good bed. In spite some noise in the morning that made us wake up too early and we couldn't sleep back , we were FULLY satisfied.
Nice neighborhood , easily accessible by bus or metro (10 to 12mn of walk)very well located !
