I recommend this unit. It was clean with modern features and located in a charming residential neighborhood with a number of good local restaurants within a five to ten minute walk. The Metro (Shaw/Howard) was within walking distance but I would not recommend the walk with luggage (unless you only carried a backpack). My wife and I were able to access Nationals Park (Cardinals Won!!! Piscotty grand slam that mostly silenced Robin Ficker!!!) and many historic sights by Metro and Uber ($8) rides. The bed was very comfortable and we slept well at night (very quiet).
Albert was responsive and accommodating. The airlines changed our flight to arrive at 9:00 AM from 12:00 PM. Albert had the unit ready for our early arrival since the previous tenants left earlier that morning.
Book the unit and enjoy your DC trip!
