This was my first time in Washington DC & my first time using Airbnb! It was definitely a good experience. Shareena was very welcoming and had a vibrant, friendly personality - very easy to get along with! I would highly recommend her. Shareena's place is exactly as described, its just outside of the city so you can have that feeling of being close enough to do anything you would like to do without having to be in the busy city the whole time.
We used Uber for transportation, it ended up being a little cheaper and more convenient than the metro. A ride from Shareena's house to the national mall is about $15.00.
