This apartment is the perfect place to stay for a couple coming into DC for sightseeing. The trains are a 5 min walk away. We had rented a car, but only used it to get to and from the airport. We took the train everywhere.
The place is spotless, and very well decorated. It was such a cozy place to come back to after a long day of activity. The neighborhood is clean and we never felt unsafe. We walked from train to apartment several times late in the evening with zero problems.
