Mark's place is beautiful and very clean. I enjoyed staying there. The neighborhood is great especially if you plan on staying in the Foggy Bottom/Georgetown area and the metro is very close by. One thing I will mention is you can very easily hear people in and around the apartment. At one point I could hear a couple standing outside the house talking and could hear the people upstairs walking/running around. I absolutely loved Mark's place I walked to Georgetown multiple times while I was there it is a very beautiful, safe neighborhood. I would recommend to anyone planning to stay in D.C.
