Our stay in Barrie's flat was far less than perfect. There was mold growing on the window sills, on the walls in the bedroom, and in the shower curtain. It was freezing cold as the heat didn't seem to be working and the windows are old and aren't sealed properly. Also, it was incredibly loud as the active street below can be heard as if you were standing on the sidewalk or had the window open.
This is clearly an investment property and hasn't been cared for to the best of Barrie's "Support Team"'s abilities.
Other than those few issues, the location is good. It's at the end of the Royal Mile and close to things like the Palace of Holyroodhouse, Arthur's Seat, and Calton Hill.
