We had the good fortune to have an extended stay at Mark's home and it is absolutely perfect. The pictures do not capture what a beautiful and thoughtfully organized and appointed home it is with a great backyard and rooftop balcony for impressive views. Mark is an ideal host. He thinks of everything to make your stay fabulous and is present for questions or concerns but never is intrusive. The location is amazing. Steps from restaurants, museums and gardens, and the Washington Harbour but still part of a quiet neighborhood. We simply cannot say enough and, although we would like to keep this our secret so we can book whenever we would like, we hope others get to have a similar experience in DC. We will be back!
