We had a wonderful time staying at Nazgol's studio! She was easy to communicate with, and the studio was clean, comfortable, equipped with everything we needed (including delicious coffee), and close to a Metro line. On our last day, our flight didn't leave until the end of the day, so they were kind enough to let us store our bags with them while we did a few more things in the city before heading to the airport. I would definitely recommend this place to friends and family traveling to DC in the future!
