We had an excellent stay in Washington, D.C.! The location of this apartment is excellent. We were able to walk to the Capitol, monuments, and museums. The complimentary metro passes also made it very easy to explore elsewhere in the city, with quick access to a nearby station. The apartment was clean and comfortable, and it had everything we could have needed during our stay. The early train running nearby during the week may be something to consider, but we really didn't mind it much.
If we were to come back to D.C. again, we'd be happy to stay here again. The check-in/check-out process is easy, and we had no problems with parking. It was just what we were hoping for!
