I stayed at Mark's place with my parents. The location was great right on the Royal Mile but quiet. The apartment was charming, awesome shower and the bedroom was comfortable for the three of us. There are about three flights of stairs that lead to the apartment but its well worth the safety, view and quiet. Several thoughtful things were provided, like outlet converters, guidebooks and breakfast items (tea, coffee, cereal, milk, juice, bread and butter). We didn't get to meet Mark but he was a great communicator in advance and his friend who greeted us was very kind and helpful. Thanks Mark!
