Isaac was very helpful, flexible and easy to reach whenever I had a question. The apartment is spacious, clean, modern and well-equipped. The bathroom is very nice with good water pressure, the bed is comfortable and the kitchen has everything you'll need. Noise from the apartment upstairs may be a concern to people sensitive to sound, but for most people this won't be a problem. The Capitol South metro station is just a 5 minute walk away, with Blue, Orange and Silver Line trains. The neighborhood feels very safe, even late at night.
Don't miss: 1) Early morning walk around the National Mall, 2) Crab cake and blueberry pancakes at Eastern Market, 3) Chicken quesadilla at Tortilla Coast (near the Capitol South Station).
