Martin's place was great for our stay in DC. The place itself was modern and clean. The location was perfect for us too, being a short walk to some nice places for dinner or drinks, and only 15 minutes or so walk to the convention center where the conference we were attending was. Martin was a great host and quick to respond to any of our questions. He was also able to provide us with a couple of guest parking permits which was super convenient for us since we drove down. Couldn't have been happier with our stay.
