David's place is a good value for the price. The Air BnB is about a half a mile, 15-minute walk from the Columbia Heights Metro that is slightly uphill. There are a lot of scooters and bikes around the metro stop that you can rent that will easily get you to the Air BnB faster.
The room is connected to a common kitchen, which is shared by two other rooms. It is convenient if you would like to cook for yourself, a definite money-saver in DC. The owners were very accommodating and were quick to respond to my messages. While the place needs some updating, it is overall a good stay for a short-term trip and a good value for the price.
