Billy, Rose and Bahas are wonderful. They welcomed me and my dad in the house and made it feel like home. The closest metro station is literally around the corner and it was super easy to get around from there. Also friendship heights is an awesome shopping area with great restaurants within walking distance. We would definitely recommend them to anyone looking for a cozy and convenient place to stay in DC.
P/S: their suggestions of places to go are golden. They have answers for every question you have about the city.
