We had an excellent experience staying at Jason's flat. His associate Armando met us at the flat, gave us a walk-through, and offered plenty of great tips for things to do and see. The apartment is spacious and was more than enough for four people. The flat is within a 15-20 minute walk of Edinburgh Castle, the Royal Mile and Calton Hill, along with the numerous bars, restaurants and shops on and north of Princes Street. I can't recommend Jason's flat highly enough; should I find myself returning to Edinburgh, I will certainly check the availability of it first.
