The location is unbeatable, very close to the Royal Mile and other highlights . The interior is well laid-out, pleasant, spacious and user-friendly. The shower system may take a bit of getting used to for neophytes. A major plus: the bedroom faces an inner courtyard and offers complete silence for a restful night's sleep. The flat has an oblique view of the castle but unluckily faces what one travel writer calls "one of the ugliest buildings in Edinburgh" (the Argyle). This has zero practical impact however, and should in no way deter prospective visitors as this was a wonderful place to stay. I wouldn't hesitate to return!
