Mark was a fantastic host! He was extremely flexible with check-in (we were driving down from Inverness and detoured over to the Malt Whiskey trail, taking longer to get to Edinburgh than anticipated) and even let us leave our bags for a bit at his home after we checked out so we could continue to explore the city more. His home is in a fantastic location, right on the Royal Mile and walking distance to just about everything. Yet, even though we were in the heart of the city, it was very quiet inside and the accommodations were fantastic. I only wish we could have stayed for more than 1 night. If you stay with Mark, you will not be disappointed!!
